Question

In the figure below, what is the length of AD?

I keep getting H, but it is not correct please help!!!

Answer 1

find the inside angle B of the smaller triangle using the base (4) and height (6)
smaller part of B = arctan(4/6) = 33.69 degrees
full B = 90 degrees - smaller B gives you the other part of B for the left hand side

so 90 - 33.69 = 56.31

now AD = 6 x tan(56.31) = 9 feet
answer is G
