dif dimoamen Homework: Section 3.6 Homework Score: 0 of 1 pt 7017(7 complete) HW 3.6.43 The angle of elevation from a point on the ground to the top of a pyramid is 22 40 The angle of elevation from a point 116 feet farther back to the top of the pyramid is 12°30. Find the height of the pyramic 40 What is the height of the pyramid? (Round to the nearest integer ) ft

Solution

tan 22 degree 40\'= h/x

h=x tan 22 degree 40\'

tan 12.5 = h/(116+x)

h=(116+x)tan12.5

(116+x)tan12.5=x tan 22 degree 40\'

116 tan 12.5 = x(tan 22degree 40\' -tan 12.5 degree)

x=131.21feet

h=131.21 tan22.67 degree=55 feet

x=116 tan12.5/(tan 22degree 40\' -tan 12.5 degree)

x=
