How can you find the length of the hypotenuse given the length of 1 side and an angle? What are the other side lengths ofthe triangle? WebIf the angles are in the ratio 1:2:3, the triangle is a 30-60-90 triangle (by using x + 2x + 3x = 180 --> x = 30). How to solve a 30 60 90 triangle - an example. Any teacher certified in Special Education in Math 7-12, can teach this lesson. 1 Find the length of one of the non-hypotenuse sides. 2 Square the length of the side. 3 Double the result of the previous step. 4 Square root the result of step 3. This is the length of the hypotenuse. More In the triangle above, the hypotenuse is the side AB which is opposite the right angle, C . Students will be able to solve for any missing side of a triangle (right) and or also construct triangles using word problems and solve for the missing side.
