Percent change =100%*(new value-old value)/(old value)
If result is positive, it is an increase. If the value is negative it is a decrease.
100%*(50-45)45=100% *(5/45) =11.11 %
Hope this helps and please mark me as brainlest and like:)
Answer:
x=64
Step-by-step explanation:
Both the semicircle that says 180, and the right angle sign in the image serve to support the idea that all parts of the figure equal 90
Therefore, it is safe to say that you need to subtract 26 from 90 in order to solve for x.
90-26 = 64

Find out the length of segment DB
<em>Note</em> In this problem it was not necessary to determine the value of x to calculate the DB segment.
Anyway, the calculation was done for didactic purposes.
