According to the question, the given parameters of a triangle Δ IJK is given below:
j = 960 inches, i = 200 inches and ∠I = 68 degree.
As we know, the sum of the angle of a triangle is 180 degree.
Therefore, ∠I + ∠J + ∠K = 180 degree
Substituting above values in the given expression, we get:
∠J + ∠K = 180 - 68 = 112 degree
For isosceles triangle, two sides are equal. Therefore, ∠J = 56 degree
Hence, the calculated value for the ∠J is 56 degree.

gig. If he has $120 saved, how many
breaking gigs will it take him to have
$400 if he doesn't spend any money?
Write AND Solve the Equation.
Answer:
7
Step-by-step explanation:
→ Write the equation
40x + 120 = 400
→ Minus 120 from both sides
40x = 280
→ Divide by 40 on both sides
x = 7
The number of breaking gigs that it takes him to have is $400 will be 7 breaking gigs.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Mr. Delgado gets paid $40 per breaking gig. If he has $120 saved. If he doesn't spend any money.

Adelaide is the employee of the month at her job. Her reward is to select at random from 4 gift cards, 6 coffee mugs, 7 DVDs, 10 CDs, and 3 gift baskets. What is the probability that an employee receives a gift card, coffee mug, or CD?
According to the question, Adelaide is the employee and she has to select a reward from four gifts. And those are 6 coffee mugs, 7 DVDs, 10 CDs and 3 gift baskets.
Now, calculate the probability that the gift is either a coffee mug or CD.
Let us assume, ‘G’ represents the gift card, ‘C’ represents the coffee mug and ‘D’ represents the CD.
The total number of items are [tex]4+6+7+10+3 = 30[/tex] items
P(G or C or D) = P(G) + P(C) + P(D)
[tex]= \frac{4}{30} + \frac{6}{30} + \frac{10}{30} = \frac{20}{30} = \frac{2}{3} = 67%[/tex]

Take has a square-shaped garage with 32 square meters of floor space. she plans to build an addition that will increase the floor space by 50%. what will be the length of one side of the new garage?
The length of one side of the new square-shaped garage is 4√3 meters.
A square is a two dimensional figure that has 4 equal sides. The area of a square can be solved by multiplying the length of its side by itself.
A = s^2
where s = side length
If the initial square-shaped garage has an area of 32 square meters and will be increased by 50%, then the new area should be 50% more than the initial area.
new floor area = 50% initial area + initial area
new floor area = 50%(32) + 32
new floor area = 16 + 32
new floor area = 48 square meters
If the new garage has a floor area of 48 square meters, using the formula for the area of a square, solve for the length of its side.
A = s^2
48 = s^2

Let h(x) be the reflection of f(x)=3 x+3 in the x -axis. What is a function rule for h(x) ?
The function rule for h(x) = -3x -3.
In mathematics, functions can be manipulated algebraically to obtain graphs of functions through certain transformations. Such transformations are reflections of the x-axis or the y-axis. To flip a function f(x) on the x-axis, multiply the whole function by a negative value to get -f(x), and to flip a function f(x) on the y axis, f(-x ), specify the x variable with a negative value. If it is reflected around the y-axis, it will stay the same, which gives h(x) = 3x + 3. Flipping around the x-axis (assuming y = 0) has the y-axis as the axis of symmetry, but it is concave down.
The function rule around the x-axis gives a complementary sign of the value of the function, so
h(x) =-3x-3 will be reflection of f(x) =3x+3

What is the inscribed angle and the circumscribed angle?An inscribed angle in geometry is the angle formed in the interior of a circle when two chords intersect on the circle. It can also be defined as the angle formed by two given points on a circle at a given point on the circle.
The measure of an inscribed angle is one-half the measure of the central angle. The measure of a circumscribed angle is 180 degrees minus the measure of the central angle.
Given: P lies outside
m ∠ABC = m ∠DBC – m ∠DBA ( Addition Postulate, Subtraction Property of Equality)
m ∠DBC = m 1/2(arc DC)
m ∠DBA = m 1/2(arc DA) (The measure of an inscribed ∠ whose side diameter is half the measure of the intercepted arc (Case 1)).

0 - 7 = 7/5(-5 - 0) is the another equation in point-slope form of the line through the points (-5,0) and (0,7)
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x
We also refer to this tan as the line's slope
If we reverse the point (-5,0) and (0,7) as (0,7) and (-5,0) line we will get another equation for (-5,0) and (0,7)
We know that point-slope form = y₂ - y₁ = m(x₂ - x₁)

Solve each formula for the indicated variable. v = s² + 1/2 s h , for h
The solution of the formula v = s² + 1/2sh for the indicated variable h is 2(v - s²)/s.
According to the given question.
We have a formula v = s² + 1/2sh.
Since, we have to solve the above formula v = s² + 1/2sh for the indicated variable h.
Therefore, the solution of the above formula v = s² + 1/2sh for the indicated variable h is given by
v = s² + 1/2sh
⇒ v - s² = 1/2sh (subtracting s² from both the sides)
⇒ 2(v - s²) = sh (multiplying both the sides by 2)
⇒ 2(v - s²)/s = h (dividing both the sides by s)
⇒ h = 2(v - s²)/s
Hence, the solution of the formula v = s² + 1/2sh for the indicated variable h is 2(v - s²)/s.

A 94.6 L gasoline with a density of 0.680 g/cm^3 has a mass of 64328 g.
Density is defined as the ratio between the mass of a substance and the volume it occupies. Denoted by ρ, density is mass per unit volume and the formula is given below:
ρ = mass / volume
Converting first the volume from L to cm^3.
1 L = 1000 cm^3
94.6 L = 94.6(1000 cm^3)
94.6 L = 94,600 cm^3
Given the density of the gasoline and its volume, solve for the mass of the gasoline using the formula for the density.
ρ = mass / volume
0.680 g/cm^3 = mass / 94,600 cm^3

Find the percent of the given number. 79 % of 623
A percentage in mathematics is a number or ratio that can be expressed as a fraction of 100.
The percent of the given number 79 % of 623 is 492.17.
What is meant by percentage?A percentage in mathematics is a number or ratio that can be expressed as a fraction of 100. The term percent comes from the Latin "per centum" which means per hundred. The symbol percentage is used to represent percentage.
Let the equation be 79 % of 623
Percentage = (value/total value) × 100 %.
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
79 % of 623 = 79/100 of 82
79/100 × 623 = 492.17
