Jackson sees a tree and wants to know how tall it is. He stands at the end of the tree's 45 foot shadow on the ground. From there he looks up and the angle of elevation up to
the top of the tree is 70 degrees. Please find the height of the tree.
Round to the nearest tenth, only enter a numerical value such as "98.4".

x = -2

y = 848

step-by-step explanation:

plug in the numbers

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
