Question

95. Measures of three angles of a Ale are 2x",( 3x + 15 ) and ( 8x - 30 ) then the measures of angles are ---
a. 30, 60, 90 b. 45, 45, 90 c. 60, 60, 60 d. none of these.​

Answer 1

a)30, 60, 90

2x+(3x+15)+(8x-30)=180

13x+(-15)=180

13x=180+15

13x=195

x=195÷13

x=15

.°.2x, 3x+15, 8x-30 = 30, 60, 90
