Question

find the trigonometric ratios of 30 degree and 60 degree​

Answer 1

Answer:

Both 30∘ and 60∘ are based on an equilateral triangle with sides of length 2 and one of the angles bisected. The 45∘ angle is based on an isosceles triangle with the equal sides having a length of 1. ⇒cosec (30∘)=1sin(30∘)=112=2, ⇒cosec (60∘)=1sin(60∘)=1√32=2√3.
