+78 What is the value of r?
Enter your answer in the box.
Round your final answer to the nearest whole number.
r = __ units
+9481 sin of an angle = length of side opposite that angle / length of hypotenuse
So in this case...
sin 53.1° = 4 / r Multiply both sides of the equation by r .
r sin 53.1° = 4 Divide both sides of the equation by sin 53.1°
r = 4 / sin 53.1° Plug this into a calculator to get...
r ≈ 5
