Step-by-step explanation:

15) 5    b. color the objects on the chalkboard green

Step-by-step explanation:

15)

This question needs the Pythagorean Theorem, which is a^2 + b^2 = c^2

a is a leg (opposite line to hypotenuse)

b is a leg (base line)

c is the hypotenuse (the diagonal line.)

3^2 + 4^2 = c^2

9 + 16 = c^2

25 = c^2

then you square root the number to the left to find c

square root of 25 is 5, since 5 x 5 is 25.
