Question

The legs of a right triangle are 3 units and 5 units. What is the length of the hypotenuse? Round your answer to the nearest hundredth. 4.00 units 2.83 units 5.83 units 8.00 units

Answer 1

5.83 units

Explanation:

from Pythagoras theorem;

a^2=b^2+c^2

where a is the hypotenuse, b is the opposite and c is the adjacent

b=3 and c=5

a^2=3^2+5^2

a^2=9+25

a^2=34

find the square root of both sides,

√a^2=√34

a=5.83units

Answer 2

The answer is NOT 4, because we're looking for the length of the hypotenuse and not one of the legs. Use the Pythagorean Theorem to solve, and you should get 5.83 units.
