4c+3=15
You need to get rid of the 3
So you minus it from each side so you
4c=12
12/4=3
So c =3
Answer: 3.75 ft
Step-by-step explanation:
30/8=3.75
So since area is A= L*W
8*3.75=30 ft2
3.906m
Step-by-step explanation:
from the topic angle of elevation and depression
putting down the above question diagrammatically
we have a triangle
The angle of elevation pad looking up = 38°
using the tangent rule TOA
TAN∅= OPPOSITE/ADJACENT
we have
tan 38° = x/5
x= tan 38° × 5
x= 0.781 * 5
x = 3.906m
The length of the carpet's side is 11 feet
Step-by-step explanation:
Step 1 :
The area covered by the carpet = 121 square feet
We need to find the length of side of carpet
Step 2 :
Since it is given that the carpet is square, the length of all sides are the same
The area is obtained by squaring the side. Hence to find the side from the given area we need to take the root of the area.
Side² = 121
Therefore side = √121 = 11 feet
Step 3 :
Answer :
The length of the carpet's side is 11 feet
