Answer:
The Height of the tower is 188.67 ft
Step-by-step explanation:
Given as :
The angle of elevation to tower = 15°
The distance travel closer to tower the elevation changes to 42° = 497 ft
Now, Let the of height of tower = h ft
The distance between 42° and foot of tower = x ft
So, The distance between 15° and foot of tower = ( x + 497 ) ft
So, From figure :
<u>In Δ ABC </u>
Tan 42° =
Or , Tan 42° =
Or, 0.900 =
∴ h = 0.900 x
Again :
<u>In Δ ABD </u>
Tan 15° =
Or , Tan 15° =
Or, 0.267 =
Or, h = ( x + 497 ) × 0.267
So, from above two eq :
0.900 x = ( x + 497 ) × 0.267
Or, 0.900 x - 0.267 x = 497 × 0.267
So, 0.633 x = 132.699
∴ x = 
Or, x = 209.63 ft
So, The height of tower = h = 0.900 × 209.63
Or, h = 188.67 ft
Hence The Height of the tower is 188.67 ft Answer
Hi there.
Each line on the graph is equivalent to: 1/6
SO we can see that n is graphed at: 1 1/6 and m is graphed at: 2 4/6
To estimate the product, let's convert each fraction into an improper fraction.
n = 1 1/6 = 7/6
m = 2 4/6 = 16/6
Multiply the improper fractions.
7/6(16/6) = 112/36 = 3 4/16 = 3 1/9 (Simplified)
So 3 1/9 is your answer.
