An arborist sights the top of a tree using a clinometer and reads the angle of elevation to be 29o. Her clinometer is 28 metres from the base of the tree and is on a tripod making it 1.5 metres above ground level. This Diagram Is Not Drawn To Scale

Calculate The Full Height Of The Tree

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

c

-by-step explanation:

it would be c

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
