Answer 1

9514 1404 393

Answer:

• x = 9
• y = 12

Explanation:

The angle marked 5x° is one of two acute angles in an isosceles right triangle, so is 45°.

5x° = 45°

x = 9 . . . . . . . divide by 5°

__

The side lengths are equal, so ...

7y -9 = 5y +15

2y = 24 . . . . . . . . add 9-5y

y = 12 . . . . . . . . . .divide by 2
