Jenna and Ava are staring up at a bird. Jenna is directly east of the bird and Ava is directly west. Jenna is 100 feet from the bird and Ava is 90 feet from the bird. Jenna and Ava are 71 feet from each other. Find Jenna's angle of elevation to the bird. Round your answer to the nearest whole degree.

I want the points ok. don't judge me

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
