Question

If angle soq=100•, angle angle qor=55•find angle sor

Answer 1

It's for triangle
100+55+x =180
155+x=180
x=180-155
x=25

Answer 2

Answer:

∠SOR = 45° or 155°.

Step-by-step explanation:

Acc to the question,

∠SOQ = 100°

∠QOR = 55°

It means there can be two possibilities:

i) Line segment RO lies in between ∠SOQ, in that case ∠SOR = ∠SOQ - ∠QOR

or, ∠SOR = 100° - 55° = 45°.

ii) Line segment RO lies in outside ∠SOQ, in that case ∠SOR = ∠SOQ + ∠QOR

or, ∠SOR = 100° + 55° = 155°.
