Question

solve it...

Prove:-
Sum of all angles p+q+s+r+t=540°​

Answer 1

Answer:

Step-by-step explanation:

WKT

Sum of angles in a triangle = 180

In a Pentagon Sum of angles = 360

Here ABCDE is a Pentagon

Now

In Tr AQS

Q + S = 180 - A   :1

In Tr BTR

T + R = 180 - B    :2

In Tr CPS

P + S = 180 - C    :3

In Tr DTQ

T + Q = 180 - D    :4

In Tr EPR

P + R = 180 - E     :5

Now 1 + 2 + 3 + 4 + 5

2 ( P + Q + R + S + T ) = 540
