Answer:

c = 24

Step-by-step explanation:

The given equation is :

$\dfrac{c}{2}-5=7$

Adding both sides by 5 both sides,

$\dfrac{c}{2}-5+5=7+5\\\\\dfrac{c}{2}=12$

Cross multiplying both sides,

$c=2\times 12$

c = 24

So, the value of c is 24.

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

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).

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