Answer:

  • ∠B = 82°

Step-by-step explanation:

To find out ∠B, we need to find out what is ∠A. We are given one clue that the outer angle of ∠A is 143°. Can we use this clue and find out ∠A? Let's find out!

  • => 180 - 143 = ∠A
  • => ∠A = 37°

Since we have found ∠A, we can now find ∠B.

  • => 61 + 37 + ∠B = 180
  • => 98 + ∠B = 180
  • => ∠B = 180 - 98
  • => ∠B = 82°

Conclusion:

We have finally found out our answer and our answer is '∠B = 82°'.
