Solve the missing angle measurement

1 answer:

7 0

You just have to subtract everything from 360. So it would be like this

360 - 105 - 80 - 75= the number you get

Jus Plug that into a calculator and you have your answer :)

Change 5'9" to 5.75 ft; let t = height of the tree
You can use ratio here (corresponding sides of similar triangles):
5 x 75/ 5 = t/165
cross multiply
5t = 5.75*165
5t = 948.75
t = 948.75/ 5
t = 189.75 ft or 189 ft 9 inches
