Each of the 2 equal sides of an isosceles triangle is twice as large as the third side. If the perimeter of the triangle is 30 cm, find the length of … Webtan 180° = tan (180° – 0) = – tan 0° = 0 {since tan 0° = 0} This value is taken from the trigonometry table. Method 2: In this method, we directly substitute the values of sin 180° and cos 180° from the table values of trigonometry ratios in the tan formula. tan 180° = sin 180°/cos 180° = 0/ (-1) = 0 Tan 180 – Theta
