<h3>What is ratio and proportion?</h3>

When comparing two quantities of the same kind, ratio is utilized.

For two numbers, a and b, the ratio formula is written as a: b or a/b.

Two or more ratios are said to be in proportion if they are all equal.

Fractions are the foundation of the concepts of ratio and proportion.

Let x is the number of hours the first mechanic worked and y is the number of hours the second mechanic worked.

∵x+y = 20

x = 20 - y

115x+100y = 2225

115(20-y) + 100y = 2225

2300 - 115y +100y = 2225

15y = 75

y = 5 hours

∴ x = 20-5

x = 15 hours

What equation can be used to find the length of AC
slavikrds [6]
ANSWER

(10)sin(40 \degree) = AC


EXPLANATION

The given triangle ABC is a right angle triangle.

Side AC of ∆ABC is opposite to the known angle which is
40 \degree

The hypotenuse of the right angle triangle ABC is 10 in.




We use the sine ratio to arrive at the required equation.


Recall that, the sine ratio is given by
\sin( \theta)  =  \frac{length \: of \: opposite \: side}{length \: of \: the \: hypotenuse}



This implies that,


\sin(40 \degree)  =  \frac{AC}{10}


We now make AC the subject to obtain,


AC = (10) \sin(40 \degree)



The correct answer is A.
