Solve for indicated side. Round to the nearest hundredth.<br> Z=
Diano4ka-milaya [45]

Answer:

z ≈ 145.62

Step-by-step explanation:

using the sine ratio in the right triangle

sin18° = \frac{opposite}{hypotenuse} = \frac{45}{z} ( multiply both sides by z )

z × sin18° = 45 ( divide both sides by sin18° )

z = \frac{45}{sin18} ≈ 145.62 ( to the nearest hundredth )

PilotLPTM [1.2K]
Here is the solution for the given problem above.
Given: 1 2/5 hour = time it takes to download a movie
            5 1/4 hours = total hours for the download
            ? = number of movies downloaded
First, we need to simplify 1 and 2/5 hour, which is 1.4 hour, and 5 1/4 is 5.25 hours. Next, to get the number of movies downloaded, we divide 5.25 by 1.4 and the result is 3.75. Round this off to a whole number and we  get 4. Approximately, you were able to download 4 MOVIES. Hope this helps.
