Question

sin 30° + cos 60° - tan 45°

Answer 1

hey there

here ur ans:

sin 30° + cos 60° - tan 45°

= ( 1/2) + ( 1/2) - 1

= ( 1 +1)/2 - 1

= 2/2 - 1

= 1 - 1

= 0..

∴0 is the answer.

"be brainly"

"be proud"

Answer 2

The value of the given trigonometric functions sin 30° + cos 60° - tan 45° is zero

Given

• sin 30° + cos 60° - tan 45°

To find

• the value of the given trigonometric expression

Solution

we are provided with trigonometric expression with angles in degree measure and are asked to find the resultant value of the sum of all these trigonometric functions.

first let us find the known values of all these trigonometric functions with their provided angles,

sin30 = 1/2

cos60 = 1/2

tan45 = 1

substituting these value in the given question, that is,

sin 30° + cos 60° - tan 45°

or, 1/2 + 1/2 -1

or, (1+ 1)/2 - 1

or, 2/2 - 1

or, 1 -1

or, 0

Therefore, the value of the given trigonometric functions sin 30° + cos 60° - tan 45° is zero
