Question

Find the value of the variable for each polygon​

Answer 1

Answer: 142º

Explanation:

Find the sum of the polygon's interior angles with the formula
`180(n - 2)` where n is the number of the polygon's sides. The polygon's sum of interior angles is 540º

Use the sum to subtract any existing angle measures in the diagram.

`e = 540 - 90 - 102 - 108 - 98`

Just to clarify, we subtract 90 from 540 as a right angle measures 90º by definition.
