Achild lies on the ground and looks up at the top of a 9-ft tree nearby. the child is 13 ft away from the tree. what is the angle of elevation from the child to the top of the tree? round to the nearest whole degree.

Angle of elevation is 35°

Step-by-step explanation:

A child lies on the ground and looks up at the top of the tree which is 9 ft of height.

Child is 13 feet away so we have to calculate the angle of elevation from child to the top of the tree.

Let the angle of elevation is ∅ then

tan ∅ =

∅ =

∅ =

∅ = 34.69° ≅ 35°

Therefore the angle of elevation is 35°

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
