Question

△BCD ​ is a right triangle. The length of the hypotenuse is 18 cm. The length of one of the legs is 14 cm.

What is the length of the other leg?

Enter your answer in the box as a decimal rounded to the nearest tenth.

Answer 1

The answer is 11.3cm

Explanation:

Answer 2

to solve the leg of a right triangles given the two other side, use the pythagorean theorem. which state that
C^2 = a^2 + b^2
where C is the hypotenuse of the right triangle
a and b are the legs of the right triangle
since the unknown is the other leg
b^2 = C^2 - a^2
b^2 = 18^2 - 14^2
b^2 = 128
b = 11.3 cm
