Answer:

a= 45

Step-by-step explanation:

all angles equal 180 degrees so you take the angle given which is 45 and the other which is a right angle, or 90 degrees and subtract 45 from 90 and you get 45 so a = 45 and you add up 45 + 45 + 90 thats 180!

Answer:

22.73% of ounces Isabella has left of her cola.

Step-by-step explanation:

Given:

Isabella has a 22 ounce cola. She drinks 17 ounces.

Now, to find the percentage of ounces Isabella has left of her cola.

Total ounces of cola = 22.

Ounces of cola Isabella drink = 17.

So, the ounces of cola she left:

Total ounces of cola - ounces of cola Isabella drink.

$=22-17$

$=5\ ounces.$

Thus, 5 ounces of cola she left.

Now, to get the percentage of cola she left:

$\frac{5}{22}\times 100$

$=\frac{500}{22}$

$=22.727\%.$

Rounding the percentage to the nearest hundredths is 22.73%.

Therefore, 22.73% of ounces Isabella has left of her cola.

Free_Kalibri [48]

80=-8a
We are trying to solve for a. So we need to get a alone. To do that we have to divide each side by -8.
80/-8= -8a/-8
Once you have solved each side you will get the following.
-10=a
