The cosine of an angle is equal to the adjacent side divided
by the hypotenuse. In a right triangle, the hypotenuse is the longest side. Its
value is 13. It also follows that B is the adjacent side.
To solve for B,
B = 13 cos 22.6˚ = 12
The tangent of the angle is equal to the opposite side
divided by the adjacent side. Since B is known, therefore the answer is
tan(22.6˚<span>) = a/12<span> </span></span>
The volume of a rectangular prism is found with the formula
V = w · l · h
So if you substitute those variables for the dimensions of the prism you get
V = 5 · 4 · 7
Then you simplify
V = 20 · 7
V = 140
Therefore, the volume of the prism is answer choice 1, 140 meters³
the answer is “s = 10w + 35” since he already has 35 but needs to find out how many weeks he washed the dishes :))
