Question

In the adjoining figure, PQ || RS, angleOAQ - 120° and angleOBS = 170°. Find the value of angle AOB​

Answer 1

Step-by-step explanation:

PQ∣∣RS and PO is transversal

∴∠SRO=∠QPR (Corresponding angles)

⇒∠SRO=70

∘

We we know exterior angle of triangle is equal to sum of interior opposite angles.

Applying this in △TRO

⇒∠RTO+∠ROT=∠SRO

⇒x+20

∘

=70

∘

⇒x=70

∘

−20

∘

=50
