Find the value of X. Then find the missing angle measures of the polygon.
Show me the steps and solve the equation
The sum of the angle measures = 180°
So we have
5x + 2x + 110 = 180
7x + 110 = 180 subtract 110 from both sides
7x = 70 divide both sides by 7
x = 10
So
5x = 5(10) = 50°
And
2x = 2(10) = 20°
Thank you!
