Question

the angle of pentagon is x,x-10°,x+20°,2x-44°,2x-70°.calculate x

Answer 1

WE KNOW THAT SUM OF ANGLES OF PENTAGON IS 360°.
SO,
$x + x - 10 + x + 20 + 2x - 44 + 2x - 70 = 540$
7x + 20 - 124= 540
7x - 104 = 540
7x = 540+104=644
x = 644/7 = 92

Answer 2

Hello dear!!!
Here's your answer....

Sum of all angles in a Pentagon is 540.

The angles given are x,x-10°,x+20°,2x-44°,2x-70°.

x+x-10+x+20+2x-44+2x-70=540
7x-104=540
7x=540+104
7x=644
x=644/7
x=92

The value of x is 92°


Hope this helps you
