Answer 1

The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate.

Angel b=angle a+angle c-180

We have now proven that all three angles of ΔABC have a measure of 60 degrees. Therfore, ∠C must have a measure of 60 degrees

Answer 2

x = -15, angle b = 115, angle c = 30.

Explanation:

The 3 sides of a triangle add up to 180, so the equation will be

35 - 5 - 8x - 2x = 180

30 - 10x = 180

Subtract 30 from both sides.

-10x = 150

Divide by -10.

x = -15.

Finding angle b:

-5 - 8x

-5 - 8(-15)

-5 + 120

115

Finding angle c:

-2x

-2(-15)

30

To check it, we add angle a, angle b, and angle c together.

35 + 115 + 30

150 + 30

180.
