Answer:
180-90=90
90÷2=45
answer is 45
Step-by-step explanation:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
<span>The solution to the problem is as follows:
y = -15x^2 + 64x + 360
400 = -15x^2 + 64x + 360
-15x^2 + 64x - 40 = 0
sol ve this for x
x = 3.5

If you would like to know what was the percent decrease in price, you can calculate this using the following steps:
x% of $299.99 is $180.55
x% * 299.99 = 180.55
x/100 * 299.99 = 180.55
x = 180.55 * 100 / 299.99
x = 60.19%
100% - 60.19% = 39.81%
The correct result would be 39.81%.
