Question

a

Find m∠POQ if ∠POQ and ∠QOR form a linear pair, as shown in the figure.
Question 1 options:

A)

155°

B)

65°

C)

335°

D)

115°

Answer 1

Answer:

155

Step-by-step explanation:

here,

∠QOR= 25

∠POQ = x

here sum of both angles is 180 ( by linear pair)

therefore,

∠QOR + ∠POQ =180

25 + x = 180

x=180-25

x=155

hence, ∠POQ= 155

Answer 2

POR is a line in which

POQ + QOR = 180°( Linear pair)

so, POQ + 25 = 180°

Then, POQ = 180 - 25

POQ = 155°

Hence proved
