Answer:
4 in.
Step-by-step explanation:
By definition of a equilateral triangle, all sides and interior angle measurements are congruent.
Essentially, all interior angles = 60°
By definition of a triangle, a triangle has 3 sides. It is given that the total measurement of the sides is 12. Divide 12 with 3: 12/3 = 4
4 inches is the side length.

9/12 times 5 is 45/ 60 which is equal to 3/4 of a mile. I’m afraid I didn’t understand the question but I hope this helps.
Answer: 7/3
Step-by-step explanation:
21/9
7/3 is the fraction in simplest form
Answer:
-3x^2 + 15x
Step-by-step explanation:
(3 - x) (x - 5)
=> (3x - 15) ( -x)
=> -3x^2 + 15x
Due to the Triangle Angle Sum Theorem, we know that the sum of the interior angles of a triangle equals 180 degrees, therefore,
180 = m<1 + m<2 + m<3
180 - m<3 = m<1 + m<2
But, we also know that m<4 + m<3 = 180 degrees.
180 = m<3 + m<4
180 - m<3 = m<4
Both m<4 and m<1 + m<2 equals 180 - m<3
m<4 = m<1 + m<2
