Question

The measurement of one angle of a right triangle is 34°.

Answer 1

We know, sum of all angles is equal to 180
Let, the missing angle = x

x + 34 + 90 = 180
x = 180 - 124
x = 56

In short, Your Answer would be 56

Hope this helps!

Answer 2

90+34=124 and a triangle equals 180 so 180-124=56 so the side should equal 56 degrees
