Problema Solution
If the largest angle in a triangle is 5 times the measure of the smallest angle, and the middle-sized angle is 20 degrees greater than twice the measure of the smallest angle, what are the three angles?
Answer provided by our tutors
let x,y,z be the angles and x the smallest
z=5x
y=20+2x
x+y+z=180
x+20+2x+5x=180
8x=160
x=20
y=20+40=60
x=5*20=100
