A right triangle has one side that measures 4 in. The angle opposite that side measures 80o. What is the length of the hypotenuse of the triangle? Round to the nearest tenth.

A: 3.9 in.

B: 4.1 in.

C: 22.7 in.

D: 23.0 in.

Verified Answer :

In order to find the length of the hypotenuse, we use knowledge on trigonometric functions which would be sine and is expressed as:

sine (theta) = opposite side / hypotenuse

sine 80 = 4 / hypotenuse
Hypotenuse = 4.1 in <---- OPTION B

The length of the hypotenuse of the triangle to the nearest tenth is 4.1 inch and it can be determine by using the trignometry function.

Given :

A right triangle has one side that measures 4 in and the angle opposite that side measures \(80^\circ\).

To determine the length of the hypotenuse of the triangle, trignometry function can be use.

\(\rm sin\theta=\dfrac{Perpendicular}{Hypotenuse}\)

\(\rm sin(80^\circ)=\dfrac{4}{Hypotenuse}\)

\(\rm Hypotenuse = \dfrac{4}{sin(80^\circ)}\)

Hypotenuse = 4.0617 inch.

The length of the hypotenuse of the triangle to the nearest tenth is 4.1 inch.
