so, it went down from 1250 to 1000, namely 1250 - 1000 = 250.

now, if we take 1250 to be the 100%, what is 250 off of it in percentage?


\bf \begin{array}{ccll}amount&\%\\\cline{1-2}1250&100\\250&x\end{array}\implies \cfrac{1250}{250}=\cfrac{100}{x}\implies 5=\cfrac{100}{x}\implies x=\cfrac{100}{5}\implies x=20

In the given figure, measure HK= 50° and measure GKL is 50° which statement is true?
Minchanka [31]

Answer: A

Step-by-step explanation:

The answer is a because the measure of angle KGH is 25 degrees since it is an inscribed angle. Angle GKJ is 130 degrees because angle GKL is 50 degrees. Therefore angle J is equal to 25 degrees which makes the triangle an isosceles triangle since angle J and angle KGH are equal to one another.
