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,

=》

$x + 2x + 3x = 180$

=》

$6x = 180$

=》

$x = \dfrac{180}{6}$

=》

$x = 30$

hence, the value of x = 30°
