A12- foot ladder is resting against a wall. the base of the ladder is 2.5 feet from the base of the wall. how high up the wall will the ladder reach. i half to use pythagorean theorem form to answer

The right triangle has legs of x and 2.5 where x is the height up the wall that the ladder will reach. The length of the ladder is the hypotenuse of the right triangle.

According to the Pythagorean Theorem, x^2 + 2.5^2 = 12^2
x = 11.736 approx To the nearest tenth that is 11.7.

the answer would be c ≈ 18.852*3.14= 6.286.28*3=18.85
