Question

In quadilateral PQRS , angle p = 120 degree and angle Q =angle R = angleS , Find angle Q, angle R and angle S​

Answer 1

Step-by-step explanation:

sum of all angles of a quardilateral = 360 deg

now let

angle Q = R = S = x deg

so

120 + x + x + x = 360

3 x = 360-120

3 x = 240

x = 240/3 = 80 deg

Answer 2

Answer:

80

Step-by-step explanation:

According to angle sum property

the sum of all angles of a quadrilateral is 360

Here

angle Q =angle R = angle S = x

and p = 120

x+x+x+120 = 360

x=80
