Question

Name an angle of

B) 50°

Answer 1

Answer: B-C

Explanation:

I believe it is the angle of B-C becuase B-E is a strieght line which equals 180. Also EFD looks the same as AFB so it is 40. And DFC is 90 becuase of the square. So we take 180-40-90=50. And the only one that is not solved is B-C

Answer 2

∠BFC = 50

Explanation:

∠AFC = 90

∠AFB + ∠BFC = 90

40 + ∠BFC = 90

∠BFC = 90 - 40

∠BFC = 50
