in degrees.
Answer:
Step-by-step explanation:
Actually, the complete question includes the expression of each hypothenuse, because the problem is about congruence between right triangle.
So, the hypothenuse for is:
.
The hypothenuse for is:
.
So, the postulate HL (Hypothenuse-Leg) states that both right triangles are equal if their hypothenuses and legs are equal. So, we have to make equal both hypothenuse expression and solve for :
Therefore, when these triangles are congruent.
