Additive inverse of any number means a number which can be added to the original number to get
Two numbers are said to be additive inverse of each other if sum of both numbers is 0. For example if 5 is the given number then -5 will be it's additive inverse. So to find additive inverse, we basically change the sign of number.
Given number p is additive inverse off -1.2 so p must be 1.2.
Sum will obviously be 0.
So to graph them on number line, we make a point at -1.2, 1.2 and at 0 for their sum.
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
