Answer:
The answer to your question is 43 ft
Step-by-step explanation:
Data
angle = Ф = 35°
length = 75 ft
height = ?
Process
To solve this problem, use trigonometric functions. The trigonometric function that relates the Opposite side (height) and the hypotenuse (length) is sine.
sin Ф = Height / length
-Solve for height
height = length x sin Ф
-Substitution
height = 75 x sin 35
-Simplification
height = 75 x 0.574
-Result
height = 43 ft
Answer:
the formula for surface area is 2(lb + bh + lh) sq is that helps :))

Answer:
$7,987.64
Step-by-step explanation:
We know,
A = Pe^(rt)
Here,
A = 11000
interest r = .08
Time t = 4
Now,
11000 = Pe^(.08 * 4)
Or, 11000 = Pe^.32
Or, 11000 / e^.32 = P
Or, 7987.6394 = P
Or, P= 7,987.64
Jerome will have to ask for $7,987.64 to his parents.
Answer:
12 :D
Step-by-step explanation:
Answer:
1) x = 15
Step-by-step explanation:
We use the Pythagorean thm for these questions. Where a and b are the legs (So order doesn't matter), and where c is the hypotenuse
1)
a² + b² = c²
9² + 12² = x²
81 + 144 = x²
x² = 225
You square root each side so you can get rid of the exponent on x.
x = 15
