To the nearest tenth, what is the length of the hypotenuse of an isosceles right triangle with a leg of 7 3 inches?

A15.7inches
B16.2 inches
C17.1 inches
D18.5 inches

Verified Answer :

Answer:

the answer is the option C

\(17.1\ in\)

Step-by-step explanation:

we know that

An isosceles right triangle has two equal legs

Let

x------> the length side of the hypotenuse

y-----> the length side of the leg

Applying the Pythagoras theorem

\(x^{2} =y^{2}+y^{2}\)

\(x^{2} =2y^{2}\)

In this problem we have

\(y=7\sqrt{3}\ in\)

Substitute and solve for x

\(x^{2} =2(7\sqrt{3})^{2}\)

\(x=17.1\ in\)
