An equilateral triangle has three equal angles.
Which equation could be used to find the
measure, m, of one angle

A 180 + 3 = m
B 3 × 180 = m
C 180 – 3 =180
D 180 ÷ 3 = m

D. 180 ÷ 3 = m

Step-by-step explanation:

The sum of the angles in a triangle adds up to 180°.

Since equilateral triangles have 3 equal angles,

sum of the angles in the triangle= 3m

3m=180°

m= 180° ÷3

m=60°

Thus, 180÷3=m

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
