Question 488700: a triangle is such that the largest angle is three times the smallest angle. the third angle is 9 degrees less than the largest angle. find the measurement of each angle Answer by cleomenius(959) (Show Source):
You can put this solution on YOUR website! The total sum of the 3 angles will be 180 degrees.
Let angle 1 = x
Let angle 2 = 3x
Let angle 3 = 3x - 9
x + 3x + 3x - 9 = 180
7x = 189.
x = 27 degrees.
angle 1 = 27 degrees.
angle 2 = 81 degrees.
angle 3 = 72 degrees.
27 + 81 + 72 = 180 degrees.
