Answer 1

Marilyn is having shelves installed to create a corner pantry. The length of one wall is 21 inches and the length of the other wall is 25 inches. The contractor who is making the shelves, which are shaped like right triangles, needs to know the measure of the angle opposite the short side of the pantry,
`\left[\begin{array}{ccc}m<A\end{array}\right]`

Question:

What is the measure of that angle? Round your answer to the nearest degree.

Answer:

40°

Explanation:

`\left[\begin{array}{ccc}m<A&=&(21)/(25)\\m<A&=&Tan^(-1)(21)/(25)\\&\\eq&40Degrees\end{array}\right]`
