Answer:
c) 190.6 ft
we first must calculate the height of the tree, and let's give it T
T = tan(47) × 130
T = 1.07.. × 130
T = 139.40.. ft
now we will calculate the distance between the top of the tree and the tip of the casted shadow, and let's give it D
D² = 130² + 139.40²
D² = 16900 + 19434.57..
D² = 36334.57..
D = √36334.57..
D = 190.6 ft
a = 30/5 = 6
Step-by-step explanation:
C
You can write the equation like this:
A - 2.5 = 1.5
If you reverse the equation, it looks like this:
1.5 - 2.5 = A
1.5 - 2.5 = 4
A = 4
Now plug the x value into 9x + 2
Hope that helps!
