Question 702673
Let m = middle angle measure
Let s = smallest angle
Let L= largest angle

the largest angle is three times the smallest angle (L=3s), and the smallest angle is 30 degrees less than the middle angle (s=m-30). What are the values of all three angles?


Those angles again,
m
s=m-30
L=3s


L=3(m-30)  [by substitution]


Requirement of a triangle, L+s+m=180
3(m-30)+(m-30)+m=180
Find m.
Compute the other two angles' measures.
