How to solve for an angle using sin
WebStep 1 Write a table listing the givens and what you want to find: Step 2 Based on your givens and unknowns, determine which sohcahtoa ratio to use. In this case we want to use tangent because it's the ratio that involves the adjacent and opposite sides. Step 3 Set up an equation based on the ratio you chose in the step 2. WebThe range of inverse sine is restricted to the first and fourth quadrants. So what this means is using the Law of Sines is only ever going to give you acute angles. If you want to find the obtuse angle, you have to subtract the acute angle from 180 or just use the Law of Sines on the smallest angle to ensure it works. ( 30 votes) Flag Show more...

WebWe then set the expressions equal to each other. bsinα =asinβ ( 1 ab)(bsinα)= (asinβ)( 1 ab) Multiply both sides by 1 ab. sinα a = sinβ b b sin α = a sin β ( 1 a b) ( b sin α) = ( a sin β) ( 1 a b) Multiply both sides by 1 a b. sin α a = sin β b. Similarly, we can compare the other ratios.
WebJul 16, 2024 · They created tables of sine values (actually chord values, in really ancient times, but that more or less amounts to the same problem) by starting with $\sin(0^\circ)=0$, $\sin(90^\circ)=1$ and then using known formulas for $\sin(v/2)$ to find sines of progressively smaller angles than $90^\circ$, and then formulas for $\sin(v+u)$ … WebThe Law of Sines can be used to solve for the sides and angles of an oblique triangle when the following measurements are known: Two angles and one side: AAS (angle-angle-side) or ASA (angle-side-angle) ... b·sin(C) = c·sin(B) Using the transitive property, we can put these two sets of equations together to get the Law of Sines: and ...
WebThe angle the cable makes with the seabed is 39°. The cable's length is 30 m. And we want to know "d" (the distance down). Start with: sin 39° = opposite/hypotenuse. Include lengths: sin 39° = d/30. Swap sides: d/30 = sin 39°. Use a calculator to find sin 39°: d/30 = 0.6293…. Multiply both sides by 30: d = 0.6293… x 30.
