Answer:

A

Step-by-step explanation:

Note

One thing you should automatically notice is that x is larger, much larger than 20. x is the hypotenuse of a right triangle

Formula

Sin(18) = opposite side / hypotenuse

Givens

Sin(18) = 0.30902

opposite = 20

hypotenuse = x

Solution

sin(18) = 20 / x                            Multiply both sides by x

x sin(18) = 20*x /x

x sin(18) = 20                              Divide by sin(18)

x sin(18) / sin18 = 20/sin(18)

x = 20 / 0.30902

answer: x = 64.72

Let Taylor's earnings be t, Andile's earnings be a and that of Favour be f.
Given that t+a+f=380. Also given that Taylor earned 40 less than Andile. That translates to t=a-40. Favour earned twice as much as Taylor.
That is, f=2t. Substitute t=a-40 into f=2t to get f=2(a-40)=2a-80.

Substitute t=a-40 and c=2a-80 into t+a+f=380 to get
a-40+a+2a-80=380.
Combining like terms, we get 4a-120=380. Adding 120 to both sides of the equation, we get, 4a=500 and dividing by 4 on both sides, we get a=125.

Since we want to know what Taylor earned, substitute a=125 back into t=a-40=125-40=85

Therefore, Taylor earned $85!

What two numbers multiply to negative 54 and add up to 3
DENIUS [597]
The roots of 54 are: 1 and 54, 2 and 27, 3 and 18, 6 and 9, then it restarts all over again.

The two numbers have to multiply up to 54, and add up to 3. 9 and 6 have a difference of 3, and the multiplied sum is negative, so this is your pair.

9 and -6 fit this criteria, since they add up to 3 and multiply to 64.
