help This text is a mathematical expression or problem statement, and it reads:"77. \(a = 7, c = 21\)"There are no graphs or diagrams associated with this text. In Problems 67–80, use the right triangle shown to the right and find the missing length. Give exact answers and approximate answers rounded to the nearest hundredth.**Diagram Explanation:**The diagram on the right is a right triangle with sides labeled as follows:- The side opposite the right angle is labeled \( c \), representing the hypotenuse.- The two other sides, which form the right angle, are labeled \( a \) and \( b \). The triangle is outlined in blue with a small square at the right angle to indicate it is a right triangle. The task is to determine the missing side length using this diagram and provide both exact and approximate values.
