Two birds sit at the top of two different trees. the distance between the first bird and a birdwatcher on the ground is 29.7 feet. the distance between the birdwatcher and the second bird is 42.1 feet.
what is the angle measure, or angle of depression, between this bird and the birdwatcher?

the angle of depression x = 44.87°

step-by-step explanation:

points to remember

trigonometric ratio

sin θ = opposite side/hypotenuse

from the we can see a right angled triangle. we have to find the value of x

to find the value of x

sin θ = opposite side/hypotenuse

sin x   = 29.7/42.1

  = 0.7055

x = sin⁻¹(0.7055)

  =   44.87°

the angle of depression x = 44.87°

65

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
