Question

Write the value of the following
a) tan 30° b) cosec 45°

plz explain step by step

Answer 1

Step-by-step explanation:

a) Tan α = sin α/cos α

So, tan 30 degrees we can write as;

Tan 30°=sin 30°/cos 30°

We know,

Sin 30° = 1/2 & Cos 30° = √3/2

∴ Tan 30° = (1/2) /(√3/2)

Tan 30° = 1/√3

Hence, the value of Tan 30 degrees is 1/√3

find the b) cosec 45

the table above will help u.
