Angles 1 and 3 are directly across from each other.
They are called vertical angles. They share only a
vertex. They always measure the same. Therefore,
if angle 1 measures 27 degrees, angle 3 will
measure
degrees.

The measure of angle 3 is 27 degrees.

Step-by-step explanation:

Given,

angle 1 = 27°

Since angle 3 is same as angle 1, the measure of angle 3 is also 27 degrees

angle 3 = 27°.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
