17, you only have to add up a few because of the x and y placements. Hope this helps you :)
X + y = 90
Let's make 'x' the bigger angle and 'y' the smaller.
X is 24 more than twice y.
x = 24 + 2y
Now plug that into the x of the first equation.
(24 + 2y) + y = 90
Combine like terms.
24 + 3y = 90
Subtract 24 from both sides.
3y = 66
Divide both sides by 3.
y = 22
The measure of the smaller angle is 22°
Hello!!
Answer- 462
Have a good rest of your day/night
increasing 20 to 40 is the same as increasing 20 by 20 (or itself), so it is a 100% increase. Decreasing 40 to 20 is the same as decreasing 40 by 1/2 or by 20. So it is a 50% increase.
when going from 20 to 40, the number is being doubled, and when youre going from 40 to 20 you are cutting the number in half.
hope this helped:)
