Question

Solve for X
X=..........................

Answer 1

X = 40

Explanation:

3x + 2x -5 -15 = 180

5x + -20 = 180

then u add 20 on both sides

5x + 0 = 200

ya the 0 is not necessary but I was showing u add 20 on both sides lol

then u divide 5 on both sides to get the x by itself

x = 40

Hope this helps dude ^-^

Answer 2

(3x -5)°+ (2x- 15)°=180°[sum of co- Interrior angles of a triangle is 180°]

or, 3x- 5 + 2x - 15=180°

or,5x - 20 = 180°

or, 5x = 180°+20

or, x = 200÷ 5

•°•x = 40°
