An 85-foot rope from the top of a tree house to the ground forms a 45 degree angle of elevation from the ground. How high is the
Feliz [49]

Answer:

\boxed{h=60.1\ ft }

Step-by-step explanation:

<u>Right Triangles </u>

They have a right angle (90°) and a longer side called the hypotenuse opposite to the right angle. The legs and the hyponetuse form two angles that must sum 90°, and they comply:

\displaystyle sin\ \alpha=\frac {opp-leg}{hypotenuse}

Where opp-leg is the opposite leg to \alpha.

The rope from the top of a tree house is 85-foot long. It's the hypotenuse (L) of the triangle it forms with the ground and the tree. The angle of 45° is opposite to the height of the tree (h).

\displaystyle sin\ \alpha=\frac {h}{L}

We can solve for h

h=L\ sin\alpha =85\ sin\ 45^o

\boxed{h=60.1\ ft }

A recipe that makes eight jumbo blueberry muffins calls for one and a half teaspoons of baking powder how much baking powder is
USPshnik [31]

If you would like to know how much baking powder is needed to make 3000 jumbo muffins, you can calculate this using the following steps:<span>

8 jumbo blueberry muffins ... 1 1/2 teaspoons of baking powder
3000 jumbo muffins ... x teaspoons of baking powder = ?

8 * x = 1 1/2 * 3000
8 * x = 3/2 * 3000
8 * x = 4500
x = 4500 / 8
x = 562.5 teaspoons

The correct result would be 562.5 teaspoons of baking powder.</span>
