We'll just give the sides a variable, the <span>hypotenuse is A, the height is B and the bottom length is C
A = 21
C = 15
This means the B = is </span>14.696938456699069 which is rounded to 15. But, this doesn't matter.
As long as we know the hypotenuse and one side we can find out that x is equal to about 45.584691402807024, round this to 46.
46 degrees is the answer.
A vertical line is always an undefined slope
I'd do this in reverse order. Mult. each of the 3 terms inside parentheses by 4:
8k^2 - 28k + 12
The larger box is 5x bigger than the smaller one.
