number 2 i think its D.
Answered by Ms. Sue
No. A? 183 degrees for one angle? But all of the angles of a triangle only add up to 180 degrees.

Please study this before you try another guess.

Answered by Ms. Sue
Is b your answer for the first or second question?
Answered by harlee
please dont get mad at me
first question
Answered by Ms. Sue
b so to find the measure of one angle, you'd multiply? Does that make sense? One angle is 3 times the total measure. Study that site again.
Answered by Ms. Sue
Remember. The total measure of all three angles in a triangle is 180 degrees. You want to find the measurement of one angle.
