WebSolving for a side in right triangles with trigonometry CCSS.Math: HSG.SRT.C.8 Google Classroom About Transcript Sal is given a right triangle with an acute angle of 65° and a leg of 5 units, and he uses trigonometry to find the two missing sides. Created by Sal Khan and Monterey Institute for Technology and Education. Sort by: Top Voted Questions WebMay 9, 2024 · Using the right triangle relationships, we know that sin α = h b and sin β = h a . Solving both equations for h gives two different expressions for h. h = bsin α and h = asin β We 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
