The diagram representing the scenario is shown below
The triangle formed is a right triangle
AB = 192 = distance from base of buiding to your feet
BC = height of building
Taking angle 23 as the reference angle,
adjacent side = 192
opposite side = BC
We would calculate BC by applying the tangent trigonometric ratio which is expressed as
tan θ = opposite side/adjacent side
By substituting the given values,
tan23 = BC/192
By crossmultiplying,
BC = 192tan23
BC = 81.499
Rounding to the nearest whole number,
height of building = 82 feet
