Answer:
see explanation
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan A =  =
 =  =
 =  , then
 , then
∠ A =  (
 ( ) ≈ 41° ( to the nearest degree )
 ) ≈ 41° ( to the nearest degree )
The sum of the angles in the triangle = 180° , then
∠ B + 41° + 90° = 180°
∠ B + 131° = 180° ( subtract 131° from both sides )
∠ B = 49°
Using Pythagoras' identity in the right triangle
AB² = BC² + AC² = 7² + 8² = 49 + 64 = 113 ( take square root of both sides )
AB =  ≈ 10.6 ( to the nearest tenth )
 ≈ 10.6 ( to the nearest tenth )
 
        
             
        
        
        
Answer: 4.8 ft
To answer this question you need to know how much shadow: actual height ratio. Flagpole is having 8 ft shadow with 20 ft actual height. The ratio should be= 8 ft: 20 ft= 0.4
Then multiply the ratio with the oak tree shadow. The equation would be:
0.4 x 12 ft= 4.8 ft
