Answer:

4.06 in.

Explanation:

4

sin(80)= ---------- multiply by X

x

x* sin(80)= 4 divide by sin(80)

4

X=------------- simplify

sin(80)

X= 4.06 in.

Answer:

The length of the hypotenuse is 4.1 in

Explanation:

By definition, the sine of an angle is:


sin(x) = (opposite\ side)/(hypotenuse)

In this case they tell us that the opposite side measures 4 inches and the angle x measures 80 °.

With this information we can find the length of the hypotenuse h


sin(80\°) =(4)/(h)\\\\h = (4)/(sin(80\°))\\\\h = 4.062\ in

Finally the length of the hypotenuse is 4.1 in
