Find the missing value:
A) 17
B) 169
C) 13
D) 7

C

Step-by-step explanation:

AB is the hypotenuse of a right triangle.

Using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AB² = 12² + 5² = 144 + 25 = 169 ( take the square root of both sides )

AB = = 13 → C

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
