Hello! The answer has to do with multiplication and 3 * 31 is 93. Adding, subtracting, and dividing will not give you the same answer. 3 * 31 = 31 * 3 demonstrates the communtative property and A is the only one that makes sense. The answer is A: 31 * 3.

Answer:

x=12

Step-by-step explanation:

The right side is a right triangle

The base is 1/2 of the bottom or 5

The height is x and the hypotenuse is 13

We can use the Pythagorean theorem

a^2 +b^2 = c^2

5^2 +x^2=13^2

25+x^2 = 169

Subtract 25 from each side

25-25+x^2 = 169-26

x^2 =144

Take the square root of each side

sqrt(x^2) = sqrt(144)

x= 12

It can give you a pretty good idea of how many degrees everything is. for example if something was 13degrees, you would be able to make an estimate because you know how much one degree is.
