Web1. The correct formula is a ⋅ b = a b cos θ. So what you really have is cos θ = − 1 3. Therefore. sin θ = 1 − cos 2 θ = 1 − 1 3 = 2 3 = 2 3. Finally, the area of the triangle is: A r e a = 1 2 ( 5 3) ( 15) 2 3 = 75 2 2. We can just multiply 2 2 to the area, and then we get the answer you posted: WebSubstituting this new expression for the height, h, into the general formula for the area of a triangle gives: where a and b can be any two sides and.

WebThe Law of Sines. The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle: a, b and c are sides. A, B and C are angles. (Side a faces angle A, side b faces angle B and. side c faces angle C). WebSin 30° = opposite side/hypotenuse side. We know that, Sin 30° = BD/AB = a/2a = 1 / 2. Therefore, Sin 30 degree equals to the fractional value of 1/ 2. Sin 30° = 1 / 2. Therefore, sin 30 value is 1/2. In the same way, we can derive other values of sin degrees like 0°, 30°, 45°, 60°, 90°,180°, 270° and 360°. WebSolve your math problems using our free math solver with step-by-step solutions.

WebExample 1: Using the values of angles from the trigonometric table, solve the expression: 2 cos 52.5º cos 7.5º Solution: We can rewrite the given expression as, 2 cos 52.5º cos 7.5º = 2 cos ½ (105)º cos ½ (15)º. Assuming A + B = 105º, A - B = 15º and solving for A and B, we get, A = 60º and B = 45º.. ⇒ 2 cos ½ (105)º cos ½ (15)º = 2 cos ½ (60º + 45º) cos ½ (60º … WebAngle bisector theorem. The theorem states that if ∠ DAB is congruent to ∠ DAC, then.
