Question

tao 45°
Sin 30° + los60°​

Answer 1

Given:

(i) The expression is  (tan 45°/sin 30°) + cos 60°

To find:

(i) The value of this expression

Solution:

Given, the expession is :

(tan 45°/sin 30°) + cos 60°   ...(1)

We know that,

tan 45° = 1, and,

sin 30° = 1/2 and,

cos 60° = sin 30° = 1/2.

Replacing these values in expression (1), we get,

So, the solution of this expression is 5/2.
