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 }

Find the value of x in the triangle shown below. x = 56° 99°​
anyanavicka [17]

Answer:

x = 25 degrees

Step-by-step explanation:

All angles in a triangle should add up to 180 degrees. So to solve for x, set up an equation where all three angles added up equals 180.

180 = 99 + 56 + x

180 = 155 + x

25 = x

The unknown angle is equal to 25 degrees.
