24
Step-by-step explanation:
2.5 divided by 2.5 equals 1. So 60 divided by 2.5 equals 24.
It says that the triangles are congruent (same size). Also, a triangle's angles add up to 180 degrees. In both of these triangles, one angle is 90° and another angle is 52°. The other angle is 180°-90°-52°=38°.
Solve these equations to find x and y: 2x+18=38, 3y+11=38
