Question

in the figure the angle between the outermost arms is 90°.This angle is further subdivided into different parts. Which of the following does not represent any of the subdivided angles​

Answer 1

Step-by-step explanation:

Given

angle between the outermost arms is 90°

so

4x-15+3x+6+2x = 90°

9x-9 = 90

9x = 90+9

x = 99÷9

x = 11

now

(4x-15)° = (4×11-15)°

= (44-15)

= 29°

(3x+6)° = (3×11+6)°

= (33+6)

= 39°

2x = 2×11

= 22°

hence. angles are = 29° , 39° , 22°
