Answer:
right
Step-by-step explanation:
a triangle usually is 180 degrees
so to find their angle you create an equation:
since angle A,B,C = 180degrees
you can write this based on the given info:
x + 2x + 3x = 180degrees
then add the x's up you get 6x
then solve for x
: 6x=180degrees
6x/6 = 180/6
x = 30
so angle A = 30
angle B = 60
angle C = 90
