The angles 30° 45° 60° are considered as

WebAnswer (1 of 2): Without air resistance, both angles (30 and 60) will give you the same range since their difference from the maximum range of 45 degrees is the same for both angles (i.e 45–30 = 60–45) but the difference is that the shot from 60 degrees will travel in the air longer, thus, if you... WebExpress each of the angles: 30°, 45°, 60°, 90°, 225° as rational multiples of π. Measuring angles in this way, it can be shown, by means of ratios, that in a circle of radius r the length of an arc subtending an angle θ measured in radians, is given by

WebThe 30°–60°–90° triangle is the only right triangle whose angles are in an arithmetic progression. The proof of this fact is simple and follows on from the fact that if α, α + δ, α + 2δ are the angles in the progression then the sum of the angles 3α + 3δ = 180°. After dividing by 3, the angle α + δ must be 60°. WebDec 21, 2024 · Trigonometric Ratios Of Some Specific Angles With Examples. (ii) 4cot 2 45º – sec 2 60º + sin 2 60º + cos 2 90º. Sol. (i) When x = 30°, we have 2x = 60° . (ii) When x = 30°, we have 2x = 60°. ⇒ 3θ = 60° ⇒ θ = 20°. Example 7: If θ is an acute angle and sin θ = cos θ, find the value of 2 tan 2 θ + sin 2 θ – 1.
