Question

A regular polygon has 18 sides. If one of its angles measures (4h − 25)°, what is the value of h?

Answer 1

Answer: h = 46.25

Explanation:

You can use the formula below to calculate the value of its interior angle:

• n = number of sides = 18

`((n-2)*180)/(n) =((18-2)*180)/(18) =(16*180)/(18) =160`

So, each one of its interior angles is equal to 160°. Set that equal to the given angle measure and solve:

`160=4h-25\\\\4h=160+25=185\\\\h=46.25`
