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 WebFeb 24, 2024 · 6. Add up the lengths of the three side lengths to find the perimeter. Recall that the perimeter P = a + b + c. Now that you know the lengths of sides a, b and c, you simply need to add the lengths together to find the perimeter. In our first example, P = 3 + 4 + 5, or 12. In our second example, P = 6 + 8 + 10, or 24 .
