Answer:
−7(2x−11)
use distributive property
-7(2x)-7(-11)
-14x+77
1. BC = 9 tan 45 = 9 ft
AC = 9 tan 60 = 9 sqrt(3) ft
AB = AC - BC = 9sqrt3 - 9 ft ~ 6.59 ft
2. G-Zoo = 200sqrt3 / tan 60 = 200 ft
G-Library = 200sqrt3 / tan 30 = 600 ft
Zoo-Library = G-Library - G-Zoo = 600 - 200 = 400 ft
The answer is 5.6! Hope I helped!
answer: infinitely many :)
The distance from building A to building C is 433m
<h3>Right angle triangle:</h3>
- A right angle triangle has one of its angle as 90 degrees. The sides can be found using trigonometric ratios.
Therefore,
sin 60° = opposite / hypotenuse
sin 60° = b / 500
cross multiply
b = 500 sin 60°
b = 500 × 0.86602540378
b = 433.0127
b = 433 meters
