One angle in a triangle has a measure that is three times as large as the smallest angle. The measure of the third angle is 10 degrees more than that of the smallest angle. Find the measure of the LARGEST angle.

Answer 1

Don't know what else I can do

just translate into Math

smallest angle --- x°
"One angle in a triangle has a measure that is three times as large as the smallest angle. "
second angle = 3x
" the third angle is 10 degrees more than that of the smallest angle"
third angle = x+10

x + 3x + x+10 = 180
5x = 170
x = 34

smallest angle , we called it x, so 34°
second angle, we called it 3x, so 102°
third angle, we called it x=10, so 44°

check: do they add up to 180 ?
34+102+44 = 180

Thanks Reiny I figured it out and did it, but I do appreciate your it.
