I need help in the following math exercises.

a and b represent the two legs of a right triangle, while c represents the hypotenuse. Find the length of the unknow side. 43) 43) a = 30 b = 40 A) c= 35 B) c = 50 C) C = 26 D) C = 49 Solve the problem. 44) Two cars leave an intersection. One car travels north; the other east. When the car traveling north had gone 9 mi, the distance between the cars was 3 mi more than the distance traveled by the car heading east. How far had the eastbound car traveled? A) 9 mi B) 12 mi C) 15 mi D) 18 mi 45) A ladder is resting against a wall. The top of the ladder touches the wall at a height of 6 ft. Find the length of the ladder if the length is 2 ft more than its distance from the wall. A) 10 ft B) 12 ft C) 6 ft D) 8 ft 46) What is the radius of the circle? 86 10 A) ~7296 B) 1824 1874 5 C) 5 D) ~7496 Find the number of subsets of the set. 47) (7, 8, 9) A) 8 B) 6 C) 3 D) 7 48) (math, English, history, science, art} A) 24 B) 28 C) 32 D) 16 Decide whether s, c, both, or neither can be placed in the blank to make a true statement. 49) (4, 5, 6) _(4, 5, 6) A) Both c and s B ) C) Neither D) C Determine whether the statement is true or false. Let A = {1, 3, 5,7} B = {5, 6, 7, 8} C = (5, 8) D = (2, 5, 8} U = {1, 2, 3, 4, 5, 6, 7, 8} 50) CCD A) True B) False
