Answer:
x=30, y=5
Explanation:
in the first triangle, with 3 congruent angles, Since their angles are congruent l, there sides are also as well. So 8y=40 y=5. This is a right triangle so angle x and the adjacent red angle both form 90 degrees. Since the red angle is a equal angular triangle. It measures 60 degrees so 60+x=90 x=30
