Question 5 of 17
Which steps show how to use the distributive property to evaluate9 - 67?
O A. 9(67) = 9(70 - 3) = 9 . 70 +9-3 = 630 + 27 = 657
O B. 9(67) = 9(70
OC. 9(67) = 9(70 – 3) =9 .70 – 3 = 630 - 3 = 627
OD. 9(67) = 9(70– 3) = 9.70- 70 3 = 630 - 210 = 420
3) =9.70 -93= 630 -27 = 603

While taking a ride in a hot-air-balloon in Napa Valley, Francisco wonders how high he is. To find
out, he chooses a landmark on the ground that is to the east of the balloon and measures the angle of
depression to be 54°. A few minutes later, after the balloon floats horizontally 100 feet east, closer to the
landmark, the angle of depression to the same landmark is determined to be 61°. Determine the height h
of the balloon. Round your answer to the nearest tenth.

a) Find the measures of ∠1, ∠2, ∠3 and ∠4:

∠1 = ________ ∠2 = ________
∠3 = ________ ∠4 = ________
b) Solve for the height of the balloon, h. You may use any
appropriate method but must show your work!
