Answer:
x=6
Step-by-step explanation:
3/2=x/4 ( you cross-multiply)
2x=12 ( divide by 2)
x=6
Answer:
-(√5)/3
Step-by-step explanation:
The tangent being negative means the sine and cosine have opposite signs. Using the identity ...
cos(o) = ±√(1 -sin(o)^2)
we find ...
cos(o) = -√(1 -(2/3)^2) = -√(5/9)
cos(o) = -(√5)/3
The correct answer is Choice D: 56.
In a right triangle, the altitude square is equal to the product of the segments that it forms with the hypotenuse.
Therefore, we can write and solve the following equation.
30^2 = 16x
900 = 16x
56 = x
<u><em>Answer:</em></u>
79.8 (Guessing)
<u><em>Step-by-step explanation:</em></u>
for the side walls, split 19 in half, and get 9.5.
9.5 + 9.5 = 19
19 + 19 + 29.2 + 12.6
(2 walls) + (bottom floor) + (height/y)
79.8
