Answer:

x = 53°

Step-by-step explanation:

Forming the equation,

→ x + (2x + 21°) = 180°

Now the value of x will be,

→ x + (2x + 21°) = 180°

→ 3x = 180° - 21°

→ x = 159°/3

→ [ x = 53° ]

Hence, the value of x is 53°.

The answer is 138
Because the angle is 180 and what I did was 2 x 21 = 42 and I did 180-42 equals to 138
