Travis is cleaning out the leaves from his parents gutters and leans a ladder against the house. He knows the ladder is 12 feet long and the base is sitting 6 feet away from the house. Just out of curiosity, Travis wonders if he can find the angle that the ladder makes with the ground. Can he? Show your work for discovering this measure.

Given the following triangle find all unknown pieces.

Solving Right Triangles

Try to use numbers that you did not have to round. (Use what is already there rather than the numbers you found)

If you have to use a rounded number, only use them one at a time.

You can use the Pythagorean Theorem to solve for one of the sides

In right triangles the two acute angles add up to 90
