Answer:
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
Answer:
A
Step-by-step explanation:
AB and CD create a 90 degree angle, so it's perpendicular
First factor x^2+13x+36 using the AC method. Then if any individual factor on the left side of the equation is equal to zero the whole expression will equal zero. After that set x+4 equal to zero and solve for x and do the same for 9. Lastly your answer is all the values of (x+4)(x+9)=0 true.
