Sin(28) = m/27
or
m = 27 x (sin(28))
That's the easy way to find it, but if they want you to use cos, that is really tricky. They give you everything that cos would show.
you could just show a^2 + b^2 = c^2
(18)^2 + b^2 = (27)^2
324 + b^2 = 729
b^2 = 405
b = square root of 405
b = 20.1246117975
The answer is acute angle
.35 = 35% because the number is out of 100, and the five is in the hundredths place
Answer is (D). -6-7x. Or to play with it a lil bit -7x-6. The numbers and coefficients and signs are all correct doesn’t matter how you form them unless “they” disagree with it
