In Figure, `A B` is a diameter of the circle such that `/_A=35^0a n d\ /_Q=25^0,` find `/_P B R`

Text Solution

Verified by Experts


In the figure,` AB` is the diameter of the circle such that
`/_A=35^0 \and\ /_Q=25^0`
`/_APB=90^0`(angle in semi circle)
So `/_BPQ=90^0`(Linear pair)
In `/_\PQB, /_PBR=/_BPQ+/_PQB`
`=>90^0+25^0=115^0`
`PBQ=115^0`
