Find the measures of the angles of a triangle if the measure of the first angle is three times the measure of the second angle and the third is 20 degrees more than the second angle!

Thanks to all that reply!

OK, so we know that the three angles of a triangle add up to 180 degrees, right?

We'll have A, B, and C represent angles 1, 2, and 3 respectively.

Since A is 3 times B and C is 20 more than B, we'll have B equal x, because it's the smallest. Thus:

A=3x
B=x
C=x+20.

Thus:
3x+x+(x+20)=180

Simplifying, we get 5x+20=180
subtract 20 from both sides:
5x=160
divide both sides by 5
x=32.
Thus A=3*32 or 96 degrees
B=32 degrees
and C=32+20 or 52 degrees

96+32+52=180 degrees

It's my sig. It's Latin for "I think, therefore I am . . . I think" Just a little philosophy joke.

You're welcome. Good luck!
