Answer:
D.
Step-by-step explanation:
The formula is Sum(n) = (n -2) 180.
Answer:
x = 3
Step-by-step explanation:
It is a perfect triangle each side is equal and each angle is equal
6x - 3 = 3x +6 = 5x
so:
6x-3 = 5x ⇒ x = 3
6x - 3 = 3x +6 = 5x = 15
Answer:
Alright angle b, d, and f are congruent to the 70 degree angle, or in other words the same. Subtract 70 from 180 and you get 110 or the sum of each remaining angles degrees. So angles a, c, g, and e are all 110 degrees.
