Question

Find the value of x then find the angle measures of the polygon 65, x, (x-5)

Answer 1

x = 60

Explanation:

Assuming that there are no secret angles unmentioned, the figure in question is a triangle, as it has 3 angles. With this knowledge, we also know that a triangle contains 180°. So, we can do the following to solve for x.

65 + x + (x - 5) = 180

2x + 60 = 180

2x = 120

x = 60
