A) Tan

B) H = 12 unit
C) Area of triangle = 41.568 unit²
As per the data mentioned in the question,
It is given that,
Angle = 60° and value of the base of the triangle =
unit
As we know that,
The value of, Tan 60°

Further, we can write it as: Tan 60° = 1.732 (As the value of

Now finding the value of h:
As we know,
TanФ

So, we can put 60 - degrees in place of the value of the angle,
We will get it as:
(As here the value of the perpendicular is mentioned as h, and the value of the base is =
unit
Further solving:
We will get it as:

So, the value of h = 12 unit
Now calculating the area of the triangle
We know that,
Area of the triangle can be found by using formula:
Area =(1/2) × Perpendicular × Base
So, putting the value of perpendicular and base for finding the area:
We will get it:
Area

Area of the triangle:

Hence Area of triangle = 41.568 unit²
