Question

find the value of x in the following figure is 40 degree 50 degree 60 degree ​

Answer 1

Answer:

x=125

Step-by-step explanation:

Let the angle beside 60 inside the polygon be y

or, 60+y=180(sum of adjacent angles on a straight line=180)

or, y=180-60

=120

Let the angle beside 50 which is inside the polygon be z

z+50=180(sum of adjacent angles on a straight line=180)

or, z=180-50

or, z=130

We are given that both x are equal

So, x+x+40+130+120=540(angles sum of pentagon=540)

or, 2x+290=540

or, 2x=540-290

or, 2x=250

or, x=250/2

or, x=125
