WebHow to tell whether a triangle is acute, right, obtuse, or not even a triangle at all. We discuss a number of examples in this free math video tutorial by Ma... WebExplanation: 45 −45 − 90 refers to the angles of the triangle. The sum of the angles is 180°. There are two equal angles, so this is an isosceles triangle. It therefore also has two equal sides. The third angle is 90°. It is a right-angled triangle therefore Pythagoras' Theorem can be used. The sides are in the ratio 1:1:√2. Web1 sep. 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 crystal alford attorney
