Answer:
Step-by-step explanation:
and also you are diviing the numbers then subtracting 9
The slope is 1/2 and the Y intercept is -3, so the equation will be Y=1/2x-3
That is a isosceles triangle, therefore x and the top angle are the same.
There’s 180 degrees in a triangle.
Therefore:
(180 - 38)/2 = x
142/2 = x
71 = x
