Answer 1

Answer:

Reflex angle ∠UOS is 220°.

Step-by-step explanation:

We know that ∠UOT = 80° (Vertically opposite angle)

Thus, we can conclude that ∠UOS = ∠UOT + ∠TOS

So, ∠UOS = 80 + 60 = 140°

We know that the total measure of angles around a point is 360°.

So, if we have to find the reflex angle ∠UOS, we must subtract it from 360°.

Therefore, reflex angle ∠UOS = 360 - 140 = 220°

I hope this helps!!
