Question

One of the legs of a right triangle measures 9 cm and the other leg measures 1 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.

Answer 1

Answer: 9.1

Explanation:

1. Pythagorean Theorem

a^2+b^2=c^2

(9)^2+(1)^2=c^2

2. Solve

81+1=c^2

82=c^2

3. Solve for c

`√(82)`=
`√(c)`

c=9.05

4. Round

c=9.1
