Answer:
cosA = 8/17
Step-by-step explanation:
cos = adjacent/hypotenuse
The number that is adjacent to angle A is 24 and the hypotenuse is 51
Plug the numbers into the cosine equation, which would look like:
Cos A = 24/51
You can simplify the fraction by dividing it by 3
So Cos A = 8/17 or 0.89130173...
Step-by-step explanation:
x^2+3x-108
= x^2+ ( 12-15)x -108
= x^2+ 12x - 15x - 108
= x(x+12) - 15 (x+12)
= (x-15) (x+12)
