Aconvex pentagon has an interior angle with measures (5x-41) find the x value

➷ Use this formula to work out the sum of interior angles:

(n - 2) x 180

n is the number of sides

(5 - 2) x 180 = 540

Now we know the sum of interior angles is 540

(5x - 12) + (2x + 100) + (4x + 16) + (6x + 15) + (3x + 41) = 540

Simplify:

20x + 160 = 540

Subtract 160 from both sides:

20x = 380

Divide both sides by 20:

x = 19

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
