Question

Using Special Angle Triangles find the exact value :

Answer 1

Answer:

Step-by-step explanation:

Trigonometric  table has the value of the trigonometric ratio of Sin, Cos ,  Tan , Csc, Sec & Cot of the angles 0° , 30°, 45° , 60°, 90°

Cos 45 = $\frac{1}{\sqrt{2} }$

Tan 30 = $\frac{1}{\sqrt{3} }$

$Csc 45 = \sqrt{2}\\\\\\Sec 60 = 2$
