Regina Falange is 173 cm tall, making her line of sight exactly 163 from the ground. She is looking at a hawk in a tree and both are on level ground. The trunk of the tree is 10 meters away from her location
and the angle of elevation from her eyeline to the hawk is 30 degrees. What is the hawk’s height above
the ground?

7.40 meters

Step-by-step explanation:

I went with 163 cm for the height as that is where the eyeline is and where she would be looking from. (h for hawk btw)

All you do is:

tan(30)=h/10

10*tan(30)=h

h≈5.77 meters

163cm is 1.63 meters, so add it to 5.77 and you will get 7.40

Oh and here's this for further help https://www.ck12.org/book/ck-12-trigonometry-concepts/section/1.13/

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
