Given that sin b 25 and ad bd find sin ∠adc
WebOct 28, 2024 · Given that line AD is an altitude of triangle ABC. Equation to find the altitude AD is: Where. BD = 3x. DC = 5x - 14. Let's solve for x: m∠ADC = 5x + 20. m∠DAC = 2x + 2. We know that m∠ADC is 90 degrees. WebSina Sinb is the trigonometry identity for two different angles whose sum and difference are known. It is applied when either the two angles a and b are known or when the sum and difference of angles are known. It can be derived using angle sum and difference identities of the cosine function cos (a + b) and cos (a - b) trigonometry identities which are some …

WebJul 18, 2024 · Note that sin(A)/a cannot give the diameter (think of the units); if one has two similar triangles ABC and A'B'C', sin(A) = sin(A'), so you would expect the radii to be *directly* proportional to the length of a side, not *inversely* proportional. Also, you can see this gives a proof of the Law of Sines, which states sin(A)/a = sin(B)/b = sin(C)/c.
