Given that triangle ABC is a right triangle, select a set of possible side length measurements
Elza [17]

Answer:

4,5,6 / 6,8,10 / 5,12,13 / ....

Step-by-step explanation:

Base on the pythagorean theorem, we have : a² + b² = c².
The first set : 4,5,6 - 4² + 5² = 6² (a possible set)
The second set : 6² + 8² = 10² (another possible set)
The last set : 5² + 12² = 13² (also possible)

There are a lot more sets, but I'll only list 3. Hope this helps :)

The value of U.S exports to China increased from $1480 million in 2011 to $2768 million
aliya0001 [1]

The percentage of increase was 87.027... %

<em><u>Explanation</u></em>

The value of U.S exports to China increased from $1480 million to $2768 million.

Suppose, the percentage of increase is  x\%

So, <u>the amount of increase</u> = x\% of 1480 =1480*\frac{x}{100}=14.8x

Thus, the equation will be......

14.8x= 2768-1480\\ \\ 14.8x=1288\\ \\ x= \frac{1288}{14.8}=87.027....

So, the percentage of increase was 87.027... %
