Step-by-step 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°

All of the angles of a triangle must add up to equal [tex]90^{\circ}[/tex].

[tex]x+2x+3x=90[/tex]

Combine the like terms. [tex]6x=90[/tex]

Divide both sides of the equation by [tex]6[/tex]. [tex]x=15[/tex]

Now we have one angle.

[tex]x=\boxed{15^{\circ}}[/tex]

[tex]2x=2*15=\boxed{30^{\circ}}[/tex]

[tex]3x=3*15=\boxed{45^{\circ}}[/tex]
