Aka
Sin = Opposite / Hypotenuse
Cos = Adjacent / Hypotenuse
Tan = Opposite / Adjacent
Then your answer to find Sin Z...
You're looking for an angle measurement so you're going to use an inverse operation.
You'd do...
Sin = 24/40
24/40 = .6
Then you'd use your inverse so...
Z°= Sin^-1(.6)
Z = 36.8698°
Rounding
Z = 36.870°
If you're using a scientific calculator. Make sure to put your calculator in degree mode to find the angle measurements and in radians to find missing side lengths.
Answer:
The slope is -5/2

Answer: x= 
Step-by-step explanation:
−(7−2x)+7=−7
To find the opposite of 7−2x, find the opposite of each term.
−7−(−2x)+7=−7
The opposite of −2x is 2x.
−7+2x+7=−7
Add −7 and 7 to get 0.
2x=−7
Divide both sides by 2.

Fraction −7/2 can be rewritten as −2/7 by extracting the negative sign.

Answer:
the answer will be table -1
Step-by-step explanation:
First remember that sum means to add. now think about the equation. we need to find 3 numbers that equal 159 when added together. And they are all consecutive odd numbers. so let's call the first number X. the second number would be X+2 since we have to jump over 1 even number. The third number would be X+4 since we have to jump over 2 even numbers. so now an equation to represent this would be X+(X+2)+(X+4)=159. Add like terms, and remember order of operations. if you need help getting the answers leave me a comment.
