Answer 1

y≈ 5.63

Explanation:

m<KLM=137

137= 47+16y

137= 47 +16y Subtract 47 on both sides.

90=16y Divide 16 on both sides.

5.625=y Round

5.63≈ y

Answer 2

y ≈ 5.63

Explanation:

m∠KLN and m∠NLM have to add up to m∠KLM

m∠KLN = 47°

m∠NLM = 16y°

m∠KLM = 137°

47 + 16y = 137

16y = 90

y = 45/8

y = 5.625

y ≈ 5.63
