The given triangle is a right angle triangle. Taking angle a as the reference angle,
hypotenuse = 8100
adjacent side = 6750
We would find angle a by applying the cosine trigonometric ratio which is expressed as
Cos# = adjacent side/hypotenuse
Thus,
Cos a = 6750/8100 = 0.833
We would find a by finding the inverse of cos 0.833
Thus,
a = cos^-1(0.833)
a = 33.59
