Using SOH CAH TOA, we know that we can find the measure of angle A by using either sin or tan. We’ll go with sin, which is opposite over hypotenuse.

The side opposite of angle A is BC, so the numerator will be 4. The side across from the 90 degrees of angle B is AC, so our denominator is 5.

Now that we have the amount of (4/5), we have to do the inverse of sin to find the angle measure. You use a scientific calculator and put in 2nd, sin (4/5), which gives you .927.

Therefore, your answer is 92.7 degrees.

−3(y+5)=15 solve this math problem
Serhud [2]

Answer:

y = -10

Step-by-step explanation:

Hey there!

To solve this you first have to distribute the -3 to y and 5. When you do this you get...

-3y - 15 = 15

Add 15 on both sides you get...

-3y = 30

Divide by -3 and you get...

y = -10

Hope this helped :)

Kylo begins to fill up a bathtub at a steady rate. When the bathtub reaches 50 gallons at 15 minutes, Kylo
attashe74 [19]

Answer:

Please find a visual representation of the scenario generated with MS Excel

Step-by-step explanation:

The given data on how Kylo fills up the bathtub with water are;

The time it takes to fill the bathtub with 50 gallons of water = 15 minutes

The time it takes to drain 30 gallons from the bathtub = 5 minutes

The time it takes to add 5 gallons of hot water = 2 minutes

The time it takes for all the water to drain out = 4 minutes

The given scenario can be represented visually on the coordinate plane, as follows;

The y-axis represents the amount of water in the bathtub in gallons

The x-axis represents the time from the when Kylo begins to fill the bathtub

The coordinates of points in the visual representation of the given scenario are therefore;

At the start, the bathtub is empty;

y = 0, x = 0

Then we have;

\begin{array}{ccc}The \ Number \  of  \ Gallons, \,  y &Time &Cumulative  \  Time, \, x\\0&0&0\\50&15&15\\20&5&20\\25&2&22\\0&4&26\end{array}

Plotting the number of gallons and the cumulative time values on MS Excel gives a visual representation of the scenario

A square piece of plywood has sides that are 10 feet long. What is the piece of plywood's area
Anuta_ua [19.1K]
I don’t really understand the question, but if you’re looking for the area, it would be 100 feet since you have to do “Side x Side”. Hope this helps!
