A 10 foot ladder is placed against the side of a brick wall as shown in figure 1 the bottom of the ladder is 8 feet from the base of the wall how high up the wall does the ladder reach

4
5
6
7
None of the above

Step-by-step explanation:

Using the pythagorean theorem, the answer is 6.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
