A roofer needs to repair some shingles on the roof of a house, and uses a 12 foot ladder to reach the roof. In order to clear the bushes, the roofer puts the ladder 5 feet out from the side of the house. What is the height of the house from the ground to the beginning of the roof?

step-by-step explanation:

659

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
