Step 1) Cross multiply 55(12) to get 825
Step 2) Cross multiply 22(n) to get 22n
Step 3) Set up your equation: 22n=825
Step 4) Solve equation by dividing 825/22= 37.5
Your anser is N=37.5

Step-by-step explanation:
use the acroname sohcahtoa
<em><u>sin </u></em><em><u>6</u></em><em><u>0</u></em><em><u>=</u></em><em><u>8</u></em><em><u>√</u></em><em><u>3</u></em><em><u>/</u></em><em><u>h</u></em>
sin60=0.8660 while 8√3=13.8564
divide both side by 0.8660
0.8660/0.8660=13.8564/0.8660
h=16.0
Answer:
Answer is B
Step-by-step explanation:
Answer:
Height of the building = 115.4 ft.
Step-by-step explanation:
Height of building = AB + 46.4 + CD + 30.5
By applying Pythagoras theorem in ΔABP,
(26)² = (10)²+ (AB)²
676 - 100 = AB²
AB² = 576
AB = 24 ft
By applying sine rule in ΔCDE,
cos(60°) = 
CD = CE × 
CD = 
CD = 14.5 ft
Total Height = 24 + 46.4 + 14.5 + 30.5
= 115.4 ft
X + y = 23000
x.08 + y.09 = 2040
x = 23000 - y
(23000 - y) .08 + y.09 = 2040
1840 - .08y + .09y = 2040
Simplify
.01y = 200
Simplify
Y = 20000
X + 20000 = 23000
X = 3000
CHECK: .08x + .09(20000) = 2040
.08x + 1800 = 2040
Simply .08x = 240
X = 3000
