1.

Lines PQ and RS intersect each other at point O. If  ∠∶ ∠=2:3, find all the angles.    ​

Answer»

Answer:

ANSWER

∠POR+∠ROQ=180

o

(Linear pair of angles)

But ∠POR:∠ROQ=5:7 (Given)

THEREFORE, ∠POR=

12

5

×180=75

o

Similarly, ∠ROQ=

12

7

×180=105

o

Now, ∠POS=∠ROQ=105

o

(VERTICALLY opposite angles)

and ∠SOQ=∠POR=75

o

(Vertically opposite angles)
