A 10-foot tree casts a 17-foot shadow directly down a slope when the angle of elevation of the sun is 42o (see figure). Find \thetaθ, the angle of elevation of the ground (to the nearest tenth of a degree).

The angle of elevation of the ground is 30.5°

Step-by-step explanation:

Height of the tree=10 foot

length of the shadow=17 foot

we have to determine the angle of elevation of the ground

The tree,  shadow and ground forms a right triangle with tree as the height, shadow as the base.

The angle of elevation of the ground θ

tanθ=opposite/adjacent

θ

The angle of elevation of the ground is 30.5°

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
