The first one you have \frac{15}{24}=\frac{x}{3} . To solve this you would multiply both sides by 3.

\frac{45}{24}=x

Then simplify by dividing the numerator and denominator by 3.

\frac{15}{8}=x (or in a mixed fraction 1\frac{7}{8})

The second one you have \frac{7}{24}=\frac{3}{x} . To solve this you would multiply both sides by x.

\frac{7}{24}x=3

Now you would divide both sides by \frac{7}{24}.

x=\frac{3}{\frac{7}{24}}

You now then multiply 3 by 24 and then divide by 7.

\frac{72}{7}

x=\frac{72}{7} (in a mixed fraction would be 10\frac{2}{7})

Find sin j? Please I don’t understand

<h3>Answer:   C) 4/8 = 0.5</h3>

=========================================================

Explanation:

The sine ratio involves the opposite over hypotenuse.

With respect to reference angle J, the opposite leg is the one furthest from the angle. So the opposite side is KL = 4. The hypotenuse is always the longest side, always opposite the 90 degree angle, so LJ = 8 is the hypotenuse.

sin(angle) = opposite/hypotenuse

sin(J) = KL/LJ

sin(J) = 4/8

sin(J) = 0.5

DC, run your finger from point d, all the way around the circle to point c. Basically, you just drew a 180 degree arc(either clockwise or counter-clockwise will work).
