The answer is 30%) because all the angles of a triangle needs to add up to 180 so 180-75-75= 30
You know from trigonometry that AB = 15 units, so the area of the larger triangle ACB is (1/2)*15*15 = 112.5 units^2.
Then the area of triangle ADE is
.. (112.5 -62.5) = 50 . . . . units^2
The distance formula is:

We are given two points in the form (x,y), so plug in the values to the distance formula:

Next we can simplify. We know that 12-12 is 0, so we can drop it from the equation, as it will not affect our answer. Also, we know that -10-15 is -25:

The square and square root cancel each other out leaving us with 25.
The answer is 25.
“Above the door” is the prepositional phrase but I can’t help you you it’s the second part, sorry.
9 years because if you do 4700 * 1.03= 4831 now do that 9 times you get 6,132.43
