(3,6). 3 units from point. 6 units from y axis.
6y + 5*(6 + 7y)
6y + 30 + 35y
41y + 30
Solution I think I’m not 100% though:/
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
