Answer:
124.80 ft
Step-by-step explanation:
Height of Daniel = 6 ft
The angle of elevation from his eyes to the top of the statue is = 68°
Daniel is 48 ft away from the base of the statue
To find the height of the statue apply the tangent of an angle formula then add height of Daniel as;
Tan 68° = h/48
h= {48 tan 68°} + 6 ft
h= 124.804168964
h= 124.80 ft
The two ys must be the same. Equate the two right hand sides.
-x + 10 = x + 2 add x to both sides.
10 = x + x + 2
10 = 2x + 2 Subtract 2 from both sides.
8 = 2x Divide by 2
x = 8/2
x = 4
Now solve for y
y = x + 2
y = 4 + 2
y = 6
Use the other equation to check it.
y = - x + 10
y = -4 + 10
y = 6
You have to use a graphing calculator to do this
Jan because if you cross multiply thats how you get it right
