tan(angle) = opposite/adjacent
tan(37) = x/14
14*tan(37) = x
x = 14*tan(37)
x = 10.5497567
x = 10.5
Answer: 10.5
Using the law of sines:
Sin(angle) = Opposite leg / hypotenuse (A to C)
Sin(63 degrees) = 15 ft / A to C
A to C = 15 / sin(63)
A to C = 15 * cosec 63 degrees.
The answer is D
Answer:
a is the answer.
Step-by-step explanation:
S- 82.492 = Perimeter base x height /2 + base
Pyramid base
b x 10h = hb /2 + b = 100
6.92586 x 6.92586 x 10 = 479.675367396/2 =239.837683698+ base 47.9675367396 =287.805220438
479.675367396- 287.805220438 = 191.870146958
Proving each rectangle pyramid side is 1/4 of 287.805220438/4 = 72 +10 height =S- 82 (S = 82.492)
then 192/2 = 96 = 100 square feet
