Answer:
<h2>x = 70°</h2><h2>y = 55°</h2><h2>z = 55°</h2>Step-by-step explanation:
Look at the picture.
We know: the sum of the angles measure in the triangle is 180°. Therefore we have the equation:
Solve it:
Angle α and β = x are the supplementary angles. Supplementary angles add up to 180°. Therefore:
