物理基礎　３力のつりあい　sincosを使わない張力の求め方

This is a problem about balance and tension. Find the tension without using sin. When the angles are 30, 60 in a right triangle, the ratio is 1:2:√3. The side opposite 30 degrees is 1, and the side opposite 90 is √3. In a 45, 45 right triangle, the ratio is 1:1:√2. The side opposite 90 is √2.
