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!!!

  1. Ms. Sue

    What do you think the answer is? Think!!

    Are you really asking for all of the answers for this test???

    2. which group of three sides lengths will form a triangle

    A. 11,5,4
    B.22,17,14
    C.28,15,10
    D.30,15,14

  3. Ms. Sue

    What about your answer for the first question?

  4. harlee

    im so sorry i dont want to go to sleep late and this is my first time posting i wont do it again i promise

  5. harlee

    i think its A.

  6. harlee

    number 2 i think its D.

  7. 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.

    Is your second question about a right triangle?

  9. harlee

    it does'nt have a triangle or anything it just says that question

  10. harlee

    b.?

    please im trying my hardest
    and i saw your link

  11. Ms. Sue

    Is b your answer for the first or second question?

  12. harlee

    please dont get mad at me
    first question

  13. 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.

  14. 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.

  15. harlee

    ohhhh

  16. harlee

    d.

  17. harlee

    by the way your not tired??

  18. Ms. Sue

    Yes, d is correct for the first question.

  19. harlee

    never mind i got it now
    thank you for helping ;)
