Question

A. 26 inches

B. 44 inches

C. 41 inches

D. 7 inches

Answer 1

Hello Maygan:: We have:

AB = 15"

BC = 24"

AC = ?

Use this Formula.

A^2 + B^2 = C^2

AB^2 + BC^2 = AC^2

15^2 + 24^2 =AC^2

= 225 +576 = AC^2

701 =AC^2

AC = SQRT(701) SQRT=Square Root

AC =26.48 Answer.

Hope this helps.
