In ΔIJK, the measure of ∠K=90°, the measure of ∠J=62°, and KI = 2.7 feet. Find the length of IJ to the nearest tenth of a foot.

IJ is 3.1 feet long, approximately.

Step-by-step explanation:

In the image attached you can observe a representation of the problem.

Notice that we must find the hypothenuse of the right triangle. So, we need to use trigonometric reasons, because we have one angle and its opposite leg, that means we can use the sine reason.

\begin{gathered}sin(62\°)=\frac{2.7}{x} \\x=\frac{2.7}{0.9} \\x\approx 3.1\end{gathered}sin(62\°)=x2.7x=0.92.7x≈3.1

Therefore, IJ is 3.1 feet long, approximately

1 is c

2 is a

3 is a

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
