Question

.In the following figure, m || QR. Then, the measure of ∠QPR is
(a) 80°
(b) 85°
(c) 75°
(d) 70°

Answer 1

(b)85°

Step-by-step explanation:

here is your answer

Answer 2

Answer:

b) 85°

Step-by-step explanation:

Given:

∠QRP = 45°  

∠QPm = 50°

QR ║m

∠QRP = ∠RPm

So ∠QRP = ∠RPm = 45°

Solution:

∠m line = 180°

∠QPR = ∠m - ∠QPm - ∠RPm

           = 180 - 50 + 45

           = 180 - 95

           = 85°

Therefore ∠QPR = 85°
