So in this case use sine to figure this out.
To convert 48 to the ratio, you gotta use a calculator unless you've memorized everything. do sin(48), which equals about 0.74.
Since Sin is opposite / hypotenuse, 5/h must equal 0.74
So do 5 / 0.74 to get about 6.76 as your answer.
Answer:
22= 70
23= 20
Add up the angles you know and subtract/add to figure out what value is missing to make it 180
Liner function is the correct term
Answer:
19 ft by 38 feets
Step-by-step explanation:
Given that :
Available fencing = 76 feets
Rectangular fencing with 3 sides
Let the 3 sides be :
x, x, y
x + x + y = 2x + y = 76
y = 76 - 2x
Area = x * y = xy
Area = (76 - 2x) * x
Area = 76x - 2x²
Take derivative of Area with respect to x ; dA
dA /dx = 76 - 4x = 0
76 - 4x = 0
-4x = - 76
x = 76 / 4
x = 19
2x + y = 76
2(19) + y = 76
38 + y = 76
y = 76 - 38
y = 38
Hence, dimension : 19feet by 38 feets
