Finding unknown angles
WebSolution: The number of sides of a pentagon is, n = 5. The sum of all 5 interior angles of a pentagon = 180 (n -2)° = 180 (5 - 2)° = 540°. The sum of the given 4 interior angles = 108°+ 120°+ 143°+ and 97°= 468°. So the … WebCalculate the angle between the clock hands at 2:20. Show Answer. The angle between any two consecutive numbers in a clock is 360° ÷ 12 = 30°. If the minute-hand is at 2 and the hour hand is at 4, the angle between them is 2 · 30° = 60°. But at 2:20, the hour hand has moved 20 minutes towards 3.
