Question

It is given that the angles of a triangle are 3xº, (2x + 20)°, and (5x- 40)°. Form an equation in x.​

Answer 1

Hey mate hope it helps you.

3x + 2x + 20 + 5x - 40 = 180

Equation: 10x - 20 = 180

Value of x :

10x - 20= 180

10x = 200

x = 20

Answer 2

Step-by-step explanation:

$by \: \: asp \: \: of \: \: triangle \\ 3x + 2x + 20 + 5x - 40 = 180 \\ 10x - 20 = 180 \\ 10x = 180 + 20 \\ x = \frac{200}{10} \\ x = 20 \\ \\ the \: angles \: of \: the \: triangle \\ 3x = 60 \\ 2x + 20 = 60 \\ 5x - 40 = 60$

I HOPE THIS MAY HELP YOU

HAVE A NICE DAY
