Question

10)

In PQRS if ∠RSP = 80° then find ∠RQT ?

A) 100° ,
B) 80°,
C)70°,
D)110°​

Answer 1

Step-by-step explanation:

We know that,

in cyclic quadrilaterals sum of opposite angles is 1800.

So, 

∠RSP +∠PQR = 1800

⇒ 800 + ∠PQR = 1800

⇒∠PQR = 1000.

Also, we know that sum of angles on a straight line is 1800,

So,

∠PQR +∠RQT = 1800

⇒ 1000 +∠RQT = 1800

⇒∠RQT = 800.

Hence, option B is the correct.

I hope this will help you dear..
