Question

I would love some help!

Answer 1

Sum of Interior angles of a Pentagon is 540°

`\\ \tt\hookrightarrow 95+3x+23+90+7x-4+9x-6=540`

`\\ \tt\hookrightarrow 3x+7x+9x+95+90+23-4-6=540`

`\\ \tt\hookrightarrow 19x+198=540`

`\\ \tt\hookrightarrow 19x=540-198`

`\\ \tt\hookrightarrow 19x=342`

`\\ \tt\hookrightarrow x=(342)/(19)`

`\\ \tt\hookrightarrow x=18`

Answer 2

• x = 18

Explanation:

Sum of interior angles of the pentagon is:

• 3x + 23 + 9x - 6 + 7x - 4 + 95 + 90 = 180(5 - 2)
• 19x + 198 = 540
• 19x = 342
• x = 342/19
• x = 18
