Answer:
13
Step-by-step explanation:
It is a parallelogram so the opposite angles are the same.
All angles sum to 360 degrees.
This means that the adjacent angles sum to 180 degrees.
4a + 11 + 9a = 180 = 13a + 11
13a = 169
a=13
69 of the coins are not nickels.
The answer is 3.12 thank me later ;)
It is called a ray.
segments have two end points. and a ray has one end point ad extends forever in one direction, and a line extends forever in both directions.
Let x represent the length
width (w): x
length (L): x
Perimeter (P) = 2L + 2w
320 = 2(x) + 2(x)
320 = x + (x)
320 = x
()320 = x
= x
120 = x
width = x
= ()120
= 40
Answer: 40m x 120m
