∠BCD = 57°
∴ ∠BDR = ∠BCD = 57° (angle that meets the chord and the tangent is equi-angular to the angle at the alternate segment)
        
             
        
        
        
Answer:
L = 5
Step-by-step explanation:
use Pythagorean Theorem:
L² + (5 )² = (10
)² = (10 )²
)²
L² + 25(2) = 100(3)
L² + 50 = 300
L² = 250
L =  =
 =  ·
 ·  = 5
 = 5
