The angles of a triangle are (2x-30)º, (2x-60)º and (x-30)º. What is the Value of x?

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

`(2x - 30) + (2x - 60) + (x - 30) = 180 \\`

`5x - 120 = 180`

Add sides 120

`5x - 120 + 120 = 180 + 120`

`5x = 300`

Divided sides by 5

`(5)/(5) x = (300)/(5) \\`

`x = 60`

Answer 2

• Answer:

x = 60°

• Explanation:

Hi there !

The sum of the angles is 180°

2x-30 + 2x-60 + x-30 = 180

2x + 2x + x = 180° + 30° + 60° + 30°

5x = 300°

x = 300° : 5

x = 60°

Good luck !
