Not sure if this correct but hope it helps

Answer 2

C

Explanation:

Exterior angle property: Exterior angle equal the sum of opposite interior angles.

3x + 7 + 4x + 16 = 100

3x + 4x + 7 + 16 = 100 {Combine like terms}

7x + 23 = 100 {Subtract 23 from both sides}

7x = 100 - 23

7x = 77 {Divide both sides by 7}

x = 77/7

x = 11

∠B = 3x + 7 = 3*11 + 7

= 33 + 7

= 40°
