Answer:
Step-by-step explanation:
a+2a+a+10=180
4a=180-10
4a=170
a=42.4°
2a=42.5*2=85°
a+10=42.5+10=52.5°
The order of the size of angles is related to the order of the length that is opposite to that angle.
angle A is across from the smallest side, 2.4.
angle C is across from the middle side, 3.2
angle B is across from the longest side, 5.5
if you think about it, angle B has to be widest angle for it to accommodate the longest length (longer it is, the more you have to open). anlge A has to be the smallest angle for it to correspond with the smallest length
The order of smallest to largest is ∠A, ∠C, ∠B
