You are standing 15 ft away from a tree. The angle of elevation from the groumd where you are standing to the top of a tree is 5
Allushta [10]

Answer:

the height of the tree is 19.2 ft

Step-by-step explanation:

Given;

distance from the foot of the tree, d = 15 ft

angle of elevation; θ = 52°

let the height of the tree = h

Make a sketch of the problem as follows;

                                  ↑

                                  ↑ h

     52°---------------------

                  15 ft

If completed to form a right triangle by adding the hypotenuse side, we can calculate the height of the tree as follows;

tan (52)=  \frac{h}{15} \\\\h = 15 \times tan(52)\\\\h = 19.2 \ ft

Therefore, the height of the tree is 19.2 ft

Find the solutions to x^2-10+36=0
klemol [59]

Answer:

Only 6

Step-by-step explanation:

We need to factor the equation to find the solution.  TO factor we need to find what times what = 36, and what plus what equals -12.

-6 times -6 = 36

and -6 + -6 = -12

So this can be factored into

(x-6)(x-6)=0

We can find the solution by setting each parentheses equal to zero.

x-6 = 0

x = 6

So the only solution is 6

I attached an image that shows an example of factoring.
