Question

B. If x', 2x°, 3x° are the angles of a triangle. Find the value of x.

please help me. ​

Answer 1

Here's the solution,

_______________

Sum of interior angles of a triangle measures 180°

So,

=》

`x + 2x + 3x = 180`

=》

`6x = 180`

=》

`x = (180)/(6)`

=》

`x = 30`

hence, the value of x = 30°
