Answer:
I found a pdf that has the lesson overview I just searched up:
Geometry 1e elayn martin gay section 4.1 types of triangles answer sheet
Answer:
2 real solutions
Step-by-step explanation:
y = -x^2 + 3x + 5
First find the the discriminant:
using b² - 4(a)(b)
(3)²- 4(-1)(5)
=9+20
=29
since the discriminant is more than 0, there are 2 real solutions
The ground is supplementary. That means it equals 180 degrees. (A circle is 360. The ground is half the circle)
So u set up the equation as
180=22x+14x
180=36x
/36 /36
5=x
But you need to find the 14x
14(5)
=70 degrees before the tree hits the ground
