Step-by-step explanation:

Answer 2

Answer:

TRUE.

Step-by-step explanation:

Sum of the length of the triangle = 9+12+15

=). 9+12+15 = 36. Right angle means 90°

ATQ:

=). 9/36 × 90° = 22.5°

=). 12/36 × 90° = 30°

=). 15/36 × 90° = 37.5°

Let's the sum of three sides of a triangle. That is equal to Right angle = 90°

22.5° + 30° + 37.5° = 90° answer.
