Question

Points P, Q, and S are collinear. What is mZRQS?
R
((x + 1)
(3x – 5)°
s

Answer 1

m∠RQS = 47°

Explanation:

The collinear points form a "straight angle," one whose measure is 180°. That is the sum of the marked values:

(3x -5) +(x +1) = 180

4x = 184

x = 46

m∠RQS = (x+1)° = (46+1)°

m∠RQS = 47°
