Question 161209: in a certain triangle the measure of one angle is double the measure of a second angle but is 10 degrees less than the measure of the third angle. [the sum of the measures of the three interior angles of a triangle is always 180 degrees.] what is the measure of each angle?: in a certain triangle the measure of one angle is double the measure of a second angle but is 10 degrees less than the measure of the third angle. [the sum of the measures of the three interior angles of a triangle is always 180 degrees.] what is the measure of each angle? Answer by vleith(1174) (Show Source):
You can put this solution on YOUR website! Let X be the first angle. You are told the second angle is X/2. The third angle is X+10.
That means the second angle is =
The third angle is =
Do those three total to 180?
