If tan A tan B tan C = 15 and tan A + tan B = 10, find tan C. Prob. 3 If 77 + 0.40x = arc tan (cot 0.25x), find x. Prob. 4 A triangular lot ABC has angles B = 50 and C = 60. Distance BC = 300 m. A line DE which is 140 m long is laid out parallel to BC with point D on the side AC and point E on the side AB.
Calculating the arc of a circle by using data that is known. Calculations of the arc, length, radius and diameter make the process of figuring out the circle and the angle of it easier GoodCalculators.com A collection of really good online calculators for use in every day domestic and commercial use!
Ticket Out the Door – Arcs and Central Angles of Circles Name each of the following. Be sure to use proper notation! EC is a diameter of the circle. 1. Semicircle 2. Minor Arc 3. Major Arc 4. Central Angle Find each of the following measures on the diagram above. 5. ∠EAD 6. BC 7. BEC 8. ECB 90 70
The radian measure of an angle θ is defined as the length, a, of the arc that subtends the angle divided by the radius, r, of the circle. = N For one complete revolution, the length of the arc equals the circumference of the circle, 2 πr. = ˜ON N =2P One complete revolution measures 2 π radians.

Let the measure of the angle be x o. Its complement will be (90 o - x o) and its supplement will be (180 o - x o). Supplement of thrice of the angle = (180 o - 3x o) According to the given information: (90 o - x o) = (180 o - 3x o) 3x - x = 180 - 90 2x = 90 x = 45. Thus, the measure of the angle is 45 o. The measure of the angle is 45 o
