Question

Find the value of x please

Answer 1

2x +5x-20+3x=180(angle of triangle)

10x-20=180

10x=180+20

10x=200

x=200/10

x=20

Answer 2

`x = 20`

Explanation:

Angles in a triangle is added up to 180 degrees

So, You can simply Solve it like this

`2x + 3x + 5x - 20 = 180 \\ 10x = 180 + 20 \\ 10x = 200 \\ (10x)/(10) = (200)/(10) \\ x = 20`

Hope this helps you.

Have a nice day!
