Question

The measure of the angles of a pentagon are (-5).(-6), (2x - 7),xº and (2x - 2)°. Find the
value of x​

Answer 1

Answer:

Step-by-step explanation:

sum of angles of a Pentagon =540degrees

x-5+x-6+2x-7+x+2x-2=540

x+x+2x+2x-20=540

7x-20=540

7x= 540+20

7x=560

x=560/7=80.

Therefore x=80 degrees.
