20 + 5 + 2 + 3 + 1 minus 1 =30
To solve this simply divide 4 by 3 and use the long division and do the same for 11 and 9, then compare the values.
We have a right triangle and an indicated angle of 59°. Opposite that angle is the height of the building, which we seek. Adjacent to that angle is the distance to the building, which we know is 63 feet.
We have a problem with opposite and adjacent so we use the tangent function.
tan 59° = h / 63
h = 63 tan 59° ≈ 104.8496074
Answer: 105 feet
