an equilateral triangle has three equal sides , which equation could be used to find the measure,M,of one angle

A.180+3=M ----
B.3 x 180
C. 180-3=180
D. 180 divided by 3=M


if you know all the answer GREAT!!!

  5. i think its A.

  6. number 2 i think its D.

  7. 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.

  12. please dont get mad at me
    first question

  13. 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.

  14. Remember. The total measure of all three angles in a triangle is 180 degrees. You want to find the measurement of one angle.
