Answer:
The length of the hypotenuse is 4.1 in
Explanation:
we know that
In the right triangle of the problem
The function sine of angle of 80 degrees is equal to divide the opposite side to the angle of 80 degrees (4 in) by the hypotenuse
Let
x ----> the hypotenuse
so
sin(80°)=4/x
isolate the variable x
x=4/sin(80°)
x=4.1 in
