Another way of asking this question would be... "20 is 80 percent of what number"?
80/100 = 20/x
reduce to lowest terms...
4/5 = 20/x
this makes it a little easier to figure out...
Divide 20 by 4, then multiply by 5 to get 25. There were 25 questions on Victoria’s test!

Answer: 25

Step-by-step explanation:

80/ 100 = 0.8

The sum of the measures of two angles is 180 degrees. One angle measures 3a and the other angle measures 2a-25 Find a. Then find
e-lub [12.9K]
The sum of the angles equal 180 degrees, so we plug the angle values into an equation:
3a + 2a - 25 = 180.
By combining like terms, this becomes:
5a - 25 = 180
Now, if we add 25 to both sides to isolate a, we get:
5a = 205
Finally, we need to divide both sides by 5 to find a, and we get:
a = 41

Yay! Now we have a. Now we just plug them into the original values! So:
2(41) - 25
Multiply out:
82 - 25
The first angle is equal to 57.

Then we use the second angle:
3(41)
Multiply out:
123
The second angle is equal to 123.

Hope this helps!
