Question

In the given figure, PQllRs and a:b = 3:2.
Find the measurement of all angles and state
the property used.​

Answer 1

Answer:

It has been given that a:b=3:2

Hence, let a=3x and b=2x

Here, a+b=180

o

[linear angles]

⇒3x+2x=180

o

⇒5x=180

o

⇒x=

5

180

o

⇒x=36

o

∴a=3×x=3×36

o

=108

o

Also, PQ parallel to RS and line l is a transversal.

∴a=f ....[ Corresponding angles ]

⇒f=108

o

Hence, option B is correct.
