Question

In the diagram, what is m NSR?

Answer 1

∠ VSR = 80°

Explanation:

∠ VSR and ∠ VSU are adjacent angles and sum to 180° , then

∠ VSR + 100° = 180° ( subtract 100° from both sides )

∠ VSR = 80°

Answer 2

RU is a line which needs to equal 180 degrees. This means angle VSR + VSU needs to equal 180.

VSU = 100

VSR = 180 - 100 = 80

Answer: VSR = 80
