Answer:
Well it is i think
Step-by-step explanation:
98.8 I don't know tho
The answer is 2 and negative 9
If the angle in B is 45º, that means the angle in A is also going to be 45º, considering it's a right triangle, so AC and BC are they have the same length.
Then using Pythagoras, you'll get that
![AC^{2} + BC^{2}](https://tex.z-dn.net/?f=%20AC%5E%7B2%7D%20%2B%20BC%5E%7B2%7D%20%20)
equals
![AB^{2}](https://tex.z-dn.net/?f=AB%5E%7B2%7D%20)
.
Now, you know that AC=BC and that AB=24.
So you'll get
![2AC^{2} =24^2](https://tex.z-dn.net/?f=2AC%5E%7B2%7D%20%3D24%5E2)
. You do the square root in both sides and you get that 2AC=24 and AC=12.
Now that you know that both AC and BC equal 12, you can find the area by just multiplying them and then diving them by 2. (The formula for the area of a triangle is half base multiplied by height, and in a right triangle, if a cathetus is the base, the other cathetus<span> will be the height)
And so the area is equal to 72.</span>

Step-by-step explanation:
<u>Use the graph to answer the following questions:</u>
When did she start using her phone?
When did she start charging her phone?
While she was using her phone, at what rate was Lin’s phone battery dying?
<u>From 100% to 40% between 2PM and 4 PM:</u>
- (100 - 40)/(4 - 2) = 60/2 = 30% per hour
