Answer: approximately 29 feet
Explanation: You need to find a tree so that the angle of elevation from the end of the shadow to top of the tree is 40 degrees.
The length of the shadow is an adjacent side and is 35.
The height of the tree is the opposite side. You could use X.
Tan ratio = opposite/adjacent
tan(40) = x/35
x = 35*tan(40) =29.37
I’m guessing it would be 21/24
Answer:
2(x+8)
If you want the second step this is it: 2x+16
x=variable
Step-by-step explanation:
Hey there! :D
Since the sides are equal in length, we know this is an isosceles triangle. It will have two equal angles.
We already know the vertex is 80 degrees, so the bottom two angles will be equal in measure. All angles in a triangle equal 180 degrees
180-80= 100
100/2= 50
x= 50
I hope this helps!
