Answer:
x=3
Step-by-step explanation:
The line of reflection would be at x=3. It’s like a mirror. The reflection is backward, but the same distance from the line of reflection, so the line needs to be halfway between the two shapes. Since C is at 4 and C’ is at 2, the line of reflection has to be at 3.

Answer:
Step-by-step explanation:
<u>Ball dropped and we start count from that moment:</u>
- 160 ft down
- 80 ft up and down
- 40 ft up and down
- 20 ft up and down, end
<u>Total distance:</u>
- 160 + 80*2 + 40*2 + 20*2 = 440 ft
Answer:
u = v - at
Step-by-step explanation:
v = u + at
v - at = u + at - at
v - at = u
u = v - at
Melissa is standing 40 ft from a tree, so m = 40 is base of the triangle.
angle of elevation (aoe) = 50°
The tree's height (h) is the side opposite the aoe (50°), therefore in trigonometry tangent 50 = opposite / adjacent. The side adjacent to that angle (50°) is the base (m). Therefore:
tan50 = h/m
And now h = m (tan50)
h = 40 (1.19) = 47.7 ft
