In the given figure, OR is the bisector of angle POS and OT is the bisector of angle OOS. If P, O and Q are colinear, then find the angle between OR and OT.
Answers
Answer:
With
Step-by-step explanation:
Let ∠ AOC = 2x
So,
∠ AOD = ∠ DOC = x
( As given OD is the bisector of ∠ AOC )
Let ∠ BOC = 2y
So,
∠ BOE = ∠ EOC = y ( As given OE is bisector of ∠ BOC )
And,
∠ DOE = 90° ( As given OD is perpendicular to OE )
We can write ∠ DOE ,
As :
∠ DOE = ∠ DOC + ∠ EOC
∠ DOC + ∠ EOC = 90° ------- ( 1 ) ( As given ∠ DOE = 90° )
x + y = 90° ( From our assumption )
∠ AOD + ∠ BOE = x + y
So,
∠ AOD + ∠ BOE = 90° --------- ( 2 )
Now we add equation 1 and 2 we get
∠ DOC + ∠ EOC + ∠ AOD + ∠ BOE = 180°
So we can say that A , O and B are colinear . ( Hence proved)
I hope after that u will get ur ans
Answer:
90
Step-by-step explanation:
the bisectors are always equal
so we can take angle qot = angle sot
let them be x . ( first equation)
we can also take angle SOR = angle ROP
so let them be y. (second equation)
so by adding both the equations
x+x+y+y=180 (by linear pair)
so this will be 2(x+y)=180
x+y=180/2
x+y=90
