To find:
Approach:
For a right triangle, for which the measure of the interior angles
Length of the longer leg (opposite to
Length of the hypotenuse (opposite to
In general
Length of the longer leg
Length of the hypotenuse
Calculation:
Given,
For a
Thus, we have
Since, if is given that
For am equilateral triangle all the three interior angles measures to be
Thus,
In the above triangle the perpendicular line segment
Into two right triangles as right the
Now, consider the right
With
In the above
