Explanation:

Angles in a triangle..all add up to 180°,

no matter what the shape of the triangle might be

So hence...,

; x + 2x + 3x = 180

; 6x = 180...then divide both sides by 6

;Hence..., x = 30

;If x = 30,then we start to substitute the x part on our angles with 30,

x = 30°

2x = 60°

3x = 90°

\huge\boxed{15^(\circ), 30^(\circ), 45^(\circ)}

All of the angles of a triangle must add up to equal
90^(\circ).


x+2x+3x=90

Combine the like terms.
6x=90

Divide both sides of the equation by
6.
x=15

Now we have one angle.


x=\boxed{15^(\circ)}


2x=2*15=\boxed{30^(\circ)}


3x=3*15=\boxed{45^(\circ)}
