Answer:
2x^2 + 2x +3
I think that this is correct
Answer:
-3
Step-by-step explanation:
You subtract y values and divide by difference in x values
2-5=-3
4-3=1
-3/1=-3
base, b = 45m
angle of elevation, aoe = 82deg
height at 86th floor, h1
height above 86th floor, h2 = 123m
total height, h = h1 + h2
using
tan (aoe) = h1/b
=》 h1 = tan (aoe) × b = tan 82 x 45 = 320.2
h = h1 +h2 = 320.2 + 123 = 443.2m
The answer would be letter b
