Find the value of each variable (3x+31)° (2x-6)°
Answer:
x = 31°Step-by-step explanation:
Angle (3x+31)° and angle (2x-6)° are supplementary angles
(3x + 31)° + (2x - 6)° = 180°
5x + 25° = 180°
5x = 155°
x = 31°
-----------------
check
3 * 31 + 31 + 2 * 31 - 6 = 180
180 = 180 (remember PEMDAS)

Trigonometry question
Answer:
[tex]\frac{8\sin 72^{\circ}\sin 34^{\circ}}{\sin 116^{\circ}}[/tex]
Step-by-step explanation:
In triangle ABD,
[tex]\sin 72^{\circ}=\frac{BD}{8} \implies BD=8 \sin72^{\circ} [/tex]
In triangle BCD,
∠CBD=34° (isosceles triangle)
∠DCB=116° (sum of angles in a triangle)
[tex]\frac{BC}{\sin 34^{\circ}}=\frac{8\sin 72^{\circ}}{\sin 116^{\circ}} \\ \\ BC=\frac{8\sin 72^{\circ}\sin 34^{\circ}}{\sin 116^{\circ}}[/tex]
Answer:
4.59 cm to nearest hundredth.
Step-by-step explanation:
Consider triangle ABD.
sin 72 = DB / 8
DB = 8 sin 72
= 7.608 cm.
Imagine a line from point C perpendicular to DB at point E.
As triangle CDB is isosceles ( DC = BC), this line will cut DB in 2
so, DE = 1/2 * 7.608 = 3.804.
Now consider triangle DCE which is a right-angled triangle at E.
cos 34 = 3.804 / DC
DC = 3.804 / cos 34
= 4.588 cm
BC = DC = 4.588.

The diagrams below show two cereal boxes of different sizes and prices. (a) big box 500 g $8.00 small box 300 g $5.40 Which of the boxes is better value for money? Show your workings.
Answer: Small box has the lowest amount when divided, that box has the best value.
Step-by-step explanation:
Given data,
Big box = 500 g
It cost is $8.00
Small box = 300 g
It cost is $ 5.40
First switch the box that's in kilograms into grams.
One kilogram=1000 grams.
Then, Big box = 500 g = $ 8.00
Small box = 300 g = $ 5.40
Next divide the amount in each box by the cost of each box.
Big box = 500/8
Big box = 62.5
Small box = 300/540
Small box = 0.5555
Therefore,
So, since small box has the lowest amount when divided, that box has the best value.

Use the Exterior Angle Inequality Theorem to list all of the angles that satisfy the stated condition.
Measures less than m∠ 5
The exterior angle (∠ 5) is larger than either remote interior angle (∠ 7 and ∠ 8).
What is meant by Exterior Angle Inequality Theorem?According to the exterior angle inequality theorem, the measure of any exterior angle of a triangle is greater than the measure of either of the opposite interior angles. The adjacent interior angle and the exterior angle are supplementary. A triangle's exterior angles add up to 360º.
A triangle's exterior angle is always greater than its two remote interior angles.
By the Exterior Angle Inequality Theorem, the exterior angle (∠ 5) is larger than either remote interior angle (∠ 7 and ∠ 8).
m ∠ 7 < m ∠ 5 and m ∠ 8 < m ∠ 5 .
Therefore, the correct answer is ∠ 7 and ∠ 8.

A rental car company charges $48 per day to rent a car and $0.08 for every mile
driven. Bilquis wants to rent a car, knowing that:
. She plans to drive 175 miles.
. She has at most $110 to spend.
Write and solve an inequality which can be used to determine x, the number of days Bilquis can afford to rent while staying within her budget.
The number of days Bilquis can afford to rent while staying within her budget is 2 days.
How to solve the inequalityThe question has the following data
amount charged = $48
Rent per mile = $0.08
The mile to drive = 175 miles.
Amount to spend = 110 dollars
The inequality would be written as
48x + 0.08(175) ≤ 110
we are to solve for the value of x
this would be
48x + 14 ≤ 110
48x ≤ 110 - 14
48x ≤ 96
We have to divide through by 48
x ≤ 96 / 48
x ≤ 2
Hence we can say that the number of days Bilquis can afford to rent while staying within her budget is 2 days.

Write the equation of the line in slope-intercept form.
(x/6) - (5/12)y = 5/8
The equation of the line in slope-intercept form is y = (2/5)x + (-3/2) .
The equation of a line in slope-intercept form can be written as follows,
y = mx + c equation 1
m in the above equation represents slope of the line and c represents the intercept.
The given equation is (x/6) - (5/12)y = 5/8 .
To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as
(x/6) - (5/12)y = 5/8
On multiplying both sides of above equation by (12/5), we will get
(2/5)x - y = 3/2
⇒ y = (2/5)x + (-3/2) equation 2
On equating equation 1 and equation 2, we will get
Slope of the line = m = 2/5
Intercept = c = -3/2

Draw a right triangle with side lengths that form a Pythagorean triple. If you double the length of each side, is the resulting triangle acute, right, or obtuse? if you halve the length of each side? Explain.
If you double or halve the length of each of Pythagorean triplet the resulting triangle will always be Right Triangle.
Pythagoras Theorem states that the sum square of two sides of triangle is equal to the square of longest side.
Let us take Pythagorean triplet as (6,8,10).
where base=6
perpendicular = 8
hypotenuse = 10
Part(a)
Let us double the length of each value
base = 12
perpendicular = 16
hypotenuse = 20
By Pythagoras Theorem

[tex]12^{2} +16^{2} =20^{2} \\ \\ 144+256=400\\ \\ 400=400[/tex]
Therefore the Triangle will be a Right Triangle as Pythagoras Theorem is satisfied.

Determine whether each set of numbers can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse, or right. Justify your answer.
15,36,39
The following set of numbers, 15, 36, and 39, can be the measures of the sides of a right triangle.
A triangle is a polygon with three sides and three vertices.
To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.
let a = 15, b = 36, and c = 39
a + b > c 15 + 36 > 39 51 > 39 True
a + c > b 15 + 39 > 36 54 > 36 True
b + c > a 36 + 39 > 15 75 > 15 True
To know what type of triangle based on the length of its side:
1. Take the sum of the squares of the two smaller sides.
15^2 + 36^2 = 1521
2. Compare it to the square of the largest side.
39^2 = 1521
1521 = 1521
If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.
if they are equal, it is a right triangle
if they are smaller, then it is an obtuse triangle.
Hence, 15, 36, and 39 can be the measure of the sides of a right triangle.

A= h(b+c) solve for b
Answer:
A=h(b+c) solve for c
First, multiply h to b and c
A = hb + hc
Then, transfer hb to the other side and change its sign from positive to negative.
A – hb = hc
To get c, Divide both sides by h
(A – hb)/h = hc/h
(A - hb)/h = c OR c = (A – hb)/h
Example. Let us assume the following. A = 500 ; h= 10;b= 20; c= ?
c = (A – hb)/h
c = (500 – (10*20))/10
c = (500 – 200)/10
c = 300/10
c = 30
To check; use the original equation given.
A = h(b+c)
A = 10(20+30)
A = 200 + 300
A = 500. same as the figure given in the example.
