Answer:
The height of the tree=8.42 m
Step-by-step explanation:
We are given that
Height of Joshua, h=1.45 m
Length of tree's shadow, L=31.65 m
Distance between tree and Joshua=26.2 m
We have to find the height of the tree.
BC=26.2 m
BD=31.65m
CD=BD-BC
CD=31.65-26.2=5.45 m
EC=1.45 m
All right triangles are similar .When two triangles are similar then the ratio of their corresponding sides are equal.


Substitute the values



Hence, the height of the tree=8.42 m
Answer:
80000
Step-by-step explanation:
Replace the x values in the equation, then solve:
[(-2)^2+4]/[(-2)^2-2(-2)-48=
(4+4)/4+4-48=
8/8-48=
8/-40=
-1/5
