Answer: 
Step-by-step explanation:
Given
The perimeter of one equilateral triangle is P
The lengths of the equilateral triangle are equal
Suppose x is the length of each side
i.e.
For this question you should first add -4d on both sides of the equation and then add +16 on both sides:
25d - 4d = 26+16
21d = 42
d = 42/21
d = 2 :)))
I hope this is helpful
have a nice day
Answer:
x = 15
Step-by-step explanation:
angles 2 and 4 are supplementary so they add up to 180
2x + 10 + 4x + 80 = 180
6x + 90 = 180
6x = 90
x = 15
the answer is 9/16 the power is distributed among both numbers
