Question

In a right triangle, the measures of the two smaller angles are (3x+6) and (2x-1). Find the measure of the smallest angle in the triangle. A.17 B.33 C.57 D.90

Answer 1

17
as in right angle one has to be 90 degree others sum should be equal to 90
so if 3x+6 and 2x-1 are smaller angle their sum should add up to 90
3x+6+2x-1=90
x=17

answer is 2x-1 is smallest=33°
