Three angles fit around a point, two of the angles are 115° and 53° , then the size of third angle would be 192° and it would be a reflex angle.

The sum of the angles around a point is 360 °

If the two angles are 115° and 53° , the sum of the two angles would be 168°

If we reduce the sum of the two angles from the total 360° , we get the size of third angle as 192°

As the size of third angle is more than 180° , so the name of the third angle is reflex angle because right angle is measured 90° , obtuse angle is measured more than 90° but less than 180° , reflex angle is measured more than 180° but less than 360° and acute angle is measured less than 90 °

Correct question is - Three angles fit around a point. Two of the angles are 115° and 53° . Work out the size of third angle and which of the words below describe the third angle

   Evaluating each series of 8 terms, the result is

∑ = 42

We solve this problem by defining, succession:

  A sequence is defined by an order of values and/or elements that have a relationship of variation as a ratio or proportion that makes them predictable.

As we can see the variation between each of the terms is:

   The initial number is -13

a1 = -13

  The final number is -23.5

an = -23.5

 Let's determine the sum of this sequence of numbers

∑ = n(a1 + an)/2

 Our values are:

-13,-14.5,-16, .......,-23.5

∑ = 8(-13 - (-23.5))/2

The solution for w in the equation is w = 2. therefore, the correct option is A; w = 2

An equation represents equality of two or more mathematical expression.

The solution of an equation refers to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.

WE have been given the equation: w + 1/2 = 1/4w + 2

Then to solve, Subtract 1/2 from both sides of the equation.

w=1/4w+1 1/2

Then Multiply both sides by 4

4w=w+6

Now Subtract w from both sides

3w=6

Now Divide both sides by 3

w=2

Therefore,  the solution for w in the equation is w = 2 , the correct option is A; w = 2

In geometry, a translation is a transformation that involves moving every point in a figure, shape, or space by the same distance in a specific direction.

A translation may either be seen as the addition of a constant vector to each point or as the movement of the origin of the coordinate system. Both of these interpretations are valid.

Generally,  You need to turn the ship such that all of the sides are aligned parallel to one another.

Move the vertices around in the shape until they are aligned properly.

The rotation should be somewhere about ninety degrees, and the translation should move the form up in a diagonal direction.

y-3=4 x is in point-slope form, it is neither in slope-intercept form nor standard form.

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

We know that  point-slope form = y₂ - y₁ = m(x₂ - x₁)

the equation looks like this in point-slope form ⇒ y-2= 4(x-0)

Here, the points are (x, y) and the points the line is passing through is

(0, 2)

y-2= 4(x-0) is in point-slope form, it is neither in slope-intercept form nor  standard form.

The sequence of the angles from least to biggest is ∠WXY < ∠YXZ < ∠WYX < ∠XZY < ∠XYZ.

A triangular is a geometry with 3 sides and three angles. The triangle has angles that sum up to 180 °.

In a triangle, if the angle is small then the opposite side will be short, and if the angle increases then the side also increases.

The sides of the triangle are in ascending order, then we have

WY < YZ < WX < XY < XZ

Then the sequence of the angles is given as,

∠WXY < ∠YXZ < ∠WYX < ∠XZY < ∠XYZ

Step-by-step explanation:

His time = 42 hours a week

Quarter of his time = one fourth of his time.

Third of his time = one third of his time

So, for dealing with complaints:

42h * 1/3 = 42h / 3 = 14h

On the phone:

42h * 1/4 = 42h / 4 = 10.5h

Answer:

a) 14 hours

b) 10.5 hours

Step-by-step explanation:

Using substitution method, the solution of the given system of equations is (2,3)

A system of equation can be solved using:

The given system of equations:

5m - n = 7  ............   (1)

3 + 3n = 6m  .............. (2)

In equation (1), subtract 5m from both sides:

5m - n - 5m = 7 - 5m

-n = 7 - 5m

Multiply by (-1)

n = 5m - 7  ...... (3)

Substitute  n = 5m - 7 into equation (2)

3 + 3n = 6m

3 + 3(5m - 7) = 6m

15m -18 = 6m

9m = 18

m = 2

Substitute back m = 2 into equation (3)

n = 5m - 7

n = 5.(2) - 7 = 3

10 miles in 30 minutes would mean Julia was riding at 20mph.

5 miles in 12 minutes would mean Alex was riding at 25mph which means Alex would've had the greater average speed.

miles per hour is a good measure for this scenario because a hour is 60 minutes and the numbers 12 and 30 go into 60 cleanly.

12*5=60

What in mathematics is the Pythagoras Theorem?

Observe the graph, the triangles are right triangles. In triangle ABC, AC = 2 and BC = 4. Use the Pythagorean

Theorem to find AB.

AB² = AC² + BC²

AB = √ AC² + BC²

AB = √ 2² + 4²

AB = √4 + 16

AB = √20

Similarly In triangle XYZ, ZX = 2 and ZY = 4. Use the Pythagorean Theorem to find XY

XY² = XZ² +  ZY²

XY = √ XZ² + ZY²

XY = √ 2² + 4²

XY = √4 + 16

XY =  √20
