All you gotta do is add up the two sides and then subtract it from 47.3 .
So 10+17.3= 27.3
47.3-27.3= 20
length of a rectangle is 6 less than 3 times its width"
L = 3W-6
"perimeter of the rectangle is 148 meters"
2L + 2W = 148
L + W = 74
(3W-6) + W = 74
4W = 80
W = 20 m
L = 3W-6 = 54 m
Answer:
A= 115 degrees
C= 50 degrees
Step-by-step explanation:
All angles are equal to 180 so the equation is:
180=4x-13+x+18+15
180=5x+20
160=5x
x=32
