Answer:</h3>
47.10
<h3>
Step-by-step explanation:</h3>
The mnemonic SOH CAH TOA reminds you that ...
... Cos = Adjacent/Hypotenuse
The value y is the length of the hypotenuse, and the given length 35 is the side adjacent to the given angle. Thus, the cosine relationship will be helpful.
Filling in the given values, we have ...
... cos(42°) = 35/y
Multiplying by y/cos(42°), we can find y to be ...
... y = 35/cos(42°) ≈ 35/0.7431
... y ≈ 47.10
Answer:
x = -1 , y = 6
or (-1, 6)
Step-by-step explanation:
First solve for "y" in the second equation:

and now, use this result as a substitution for "y" in terms of "x" in the first equation:

Knowing the value of "x", now we place it in the substitution equation to find "y":

Answer:
A. $1,810, B. $16,290
Step-by-step explanation:
A. $18,100 * 0.10 = $1,810
B. $18,100 - $1810= $16,290
