Question

Find the angle measure

Answer 1

Step-by-step explanation:

By Exterior Angle theorem,

80° + (6y + 3)° = (155 - 2y)°.

=> 6y + 83 = 155 - 2y

=> 8y = 72

=> y = 9.

Answer 2

Answer:

Step-by-step explanation:

(6y + 3)° + 80° = (155 - 2y)°

6y + 3 + 80 = 155 - 2y

8y = 155 - 83

y = 9

m∠NML = 57°

m∠NLK = 137°
