Question

In a quadrilateral PQRS angle P =100° angle Q=110° angle S=65° find angle R​

Answer 1

Hey there !

The sum of the angles of the quadrilateral is 360°

So ,

< P + < Q + < R + <S = 360°

100 + 110 + R + 65 = 360

R + 275 = 360

R = 360-275

R = 85°

# hope it helps ! :)

Answer 2

Answer:

85°

Step-by-step explanation:

As the interior angle of a quadrilateral is 360°,then-

100+110+65+x=360°

275+x=360°

x=360-275

x=85°
