Answer:
25
Step-by-step explanation:
We can use the Pythagorean theorem to determine the length of the hypotenuse
a^2 + b^2 = c^2
15^2 + 20 ^2 = c^2
225 + 400 = c^2
625 = c^2
Take the square root of each side
sqrt(625) = sqrt(c^2)
25 = c
1.666666666666667 to be exact, but rounded it is 1.66
2/32. Divide 32 by 4 to equal 8, and then divide 8 by 3 because that’s how much you painted, a third of a fourth
