Answer:
Step-by-step explanation:
tan15 * tan75 * tan65*tan25*tan60 - tan30
= tan15* cot(90-75)*tan25*cot(90-65)*tan60 - tan30
=tan15*cot15*tan25*cot25*tan60-tan30
=1*1*tan60-tan30
= root3 - 1/root3
(3-1)/root3

Answer:
The required answer is .
Step-by-step explanation:
Given:
To find: Evaluate values.
Tangent theta: The side opposite theta divided by the side next to theta is known as the tangent theta. This is theta, then. This length divided by this length, or over is the tangent theta. However, because it can only be defined in this way on right triangles, this definition only applies to acute angles, which are angles between and degrees.
We have
Now calculate value.
Here,
Now, calculate the value of
Then,
Hence, the required answer is .
