Answer:

x = 9cm

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2 + x^2 = ( sqrt(117) ^2)

36 + x^2 = 117

Subtract 36 from each side

x^2 = 117 -36

x^2 = 81

Take the square root of each side

sqrt(x^2) = sqrt(81)

x = 9

Answer:

a^2 + b^2 = c^2

x^2 + 6^2 = (square root 117)^2

x^2 = square root 117 ^2 - 6^2

x^2= 117 -36

x^2 = 81

x= 9

Suppose that $3$ is a factor of $a$, $a$ is a divisor of $12$, and $a$ is positive. What is the number of possible values of $a$
antiseptic1488 [7]

If a is a divisor of 12, then

a \in \{-12, -6, -4, -3, -2, -1, 1, 2, 3, 4, 6, 12\}

If 3 is a factor (i.e. divisor) of a, then a can only be one of the elements of this set that are multiples of 3, so

a \in \{-12, -6, -3, 3, 6, 12\}

But a is positive, so there are 3 possible values a can have.
