Step-by-step explanation:
6/9 divide top and bottom by 3 to get 2/3
Now reduce each of the fractions to the lowest terms, and look for one that gives 2/3.
12/8 = 3/2 (divide by 4 top and bottom)
8/12 = 2/3 (divide by 4 top and bottom) This is a solution
10/12 = 5/6 (divide by 2 top and bottom)
8/13 (cannot be reduced)
Therefore the second fraction (8/12) forms a proportion with 6/9.
You don't really need to do any calculations for this as the picture gives it away, but let's just understand the important concept behind this. Basically, tangent is opposite divided adjacent. So for this question:

When you solve for x, you are left with:

Then you need to add the 5 because his eyes cover up the bottom part of the tree, and therefore, your answer is D.
(leftover = land - house) area
7x*11x - 2x*3x = 77x -6x
left= 77x^2
Answer:
the area of the parallelogram is 120 units
