The cosine of A is (adjacent side)/(hypotenuse) = 55/73. Do the division, then find the angle whose cosine is that number. The whole thing takes maybe 6 or 7 seconds with your calculator. It's choice-B.
Answer:
165.628° (The 8 has a line over it signalizing that it repeats forever, but I didn't know how to put it in.)
Step-by-step explanation:
Since 165 is whole number, it is a full degree. Since each minute is equal to 1/60 degrees, you need to multiply 37 by 1/60. Since each second is equal to 1/3600 degrees, multiply it 1/3600 by 44. Add them all together.
165 + 37 x 1/60 + 44 x 1/3600
simplify: 74533/450
Convert the fraction into a decimal by dividing the numerator by the denominator and you get 165.628° (with a repeating 8).
Answer:
5,816
Step-by-step explanation:
use P.E.M.D.A.S
P) parenthesis
E) exponents
M/D) multiply and divide (whichever comes first from left to right)
A/S) addition and subtract (same as multiply and divide)
Answer:
3 x -3y = -9y
3 x -1 = -3
The factored expression is 3(-3y - 1)
Step-by-step explanation:
All you have to do is -9y / 3 = -3y and -3 / 3 = -1, then put those numbers in parentheses. All of that is multiplied by 3.
The reason is because if you distributed the 3 it would become:
3 * -3y + 3 * -1 = -9y - 3
