Answer:(x+3) 2−7
Step-by-step explanation:
Well, you don't have any options.
But a mixed number for 12.16 would be 12 4/25. Hope it helps! :)
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
He spend one hour and twenty five minutes (1:25)
