Answer:

24ft

Step-by-step explanation:

Pythagorean Theorem!!

a^2 + b^2 = c^2

------------------------

In this case, the ladder is c, and the base is b.

------------------------

Plug the numbers in the formula.

a^2 + 7^2 = 25^2

------------------------

Solve.

a^2 + 49 = 625

a^2 -49 = 625 - 49

a^2 = 576

\sqrt{a^2} = \sqrt{576}

a = 24

  • 3x = 195
  • x = 65

<u>Find y:</u>
