Question

What is the measure for these (congruence and similarity) ​

Answer 1

Explanation:

4) 64° + 83° + ∠ACB = 180° ( angle sum property of triangle)

147° + ∠ACB = 180°

∠ACB = 180° -147°

∠ACB = 33°

5) 101° + 40° + ∠EFD = 180° ( angle sum property of triangle)

141° + ∠EFD = 180°

∠EFD = 180° -141°

∠EFD = 39°
