posted by .

in a triangle XYZ,the measure of angle Y is 40 more than the measure of angle X.the measure of angle Z is 10 less than three times the measure of angle X.find the measure of angle X

• algebraic equation and inaqualities -

Y = X+40
Z = 3X-10

X+Y+Z = 180
X + X+40 + 3X-10 = 180
5X = 150
X = 30
