Question

What is the measure of x?

Answer 1

`\huge\boxed{\sf x = 35}`

Explanation:

Statement:

In a polygon having 5 sides, the sum of internal angles equals 540 degrees.

Solution:

According to the statement:

2x + 9 + 4x - 1 + 88 + 110 + 3x + 19 = 540

• Combine like terms

2x + 4x + 3x + 9 - 1 + 88 + 110 + 19 = 540

9x + 225 = 540

• Subtract 225 from both sides

9x = 540 - 225

9x = 315

• Divide both sides by 9

x = 315/9

x = 35

`\rule[225]{225}{2}`
