Answer:
64.62°
Step-by-step explanation:
Use good 'ol SOHCAHTOA. Since we know the hypotenuse and the adjacent values, we use cosine.
Therefore:

Take the inverse cosine of each side:

Inverse cosine of cosine cancel each other out:

Use a calculator:

Therefore the angle is 64.62°
Y=3x^2-15x-x+5=3x^2-16x+5
(3x-1)(x-5)
-5(x^2+12+36)+22=-5x^2-24-180+22=
=-5x^2-182
Answer:
1:5
Step-by-step explanation:
He rode one mile in 5 minutes because 4/4 is 1 and 20/4 is 5
Step-by-step explanation:
well, we just do the multiplication and simplify by combining terms with the same base :
10(-5x + 3) - 2x = -50x + 30 - 2x = -52x + 30
