Answer :

MHANIFAGO

Answer:

  • 138°

Step-by-step explanation:

Sum of supplementary angles is 180°

  • m∠A + m∠B = 180°

Find the value of x

  • 2x - 24° + 5x - 27° = 180°
  • 7x - 51° = 180°
  • 7x = 180° + 51°
  • 7x = 231°
  • x = 231°/7
  • x = 33°

Find the measure of ∠B

  • m∠B = 5*33° - 27° = 138°

Supplementary angles have sum 180°

  • 2x-24+5x-27=180
  • 7x-51=180
  • 7x=231
  • x=33

<B

  • 5(33)-27
  • 138°
