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!!!

What do you think the answer is? Think!!

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

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.

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

10. harlee

b.?

11. Ms. Sue

12. harlee

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.

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 ;)

You're welcome.
