Answer:
5/16
Step-by-step explanation:
P(tails) = 1/2
P(>3) = 5/8
P(tails AND >3) = 1/2 × 5/8 = 5/16
 
        
             
        
        
        
5 x 13
65 x 1
This isn't the only factorization, there's also the 65 and 1.
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
1). In ΔABC,
    For angle A as a reference angle,
    Opposite side of ∠A → BC
    Adjacent side of ∠A → AC
    Hypotenuse → AB
2). By using tangent ratio in ΔYWZ,
     tan(72°) = 
     tan(72°) = 
     x = 
     x = 3.899
     x ≈ 3.9
3). By using sine rule in ΔKNM,
     tan(x°) = 
     tan(x) = 
     x = 
     x = 19.03
     x ≈ 19.0°
4). By applying cosine ratio in ΔJKF,
     tan(70°) = 
     tan(70) = 
     x = 
     x = 21.838
     x ≈ 21.8
 
        
             
        
        
        
Answer:
AREA =18
Step-by-step explanation
think of a rectangle, 12 by 3 which is also 12*3 
so you do 12*3=36
but since it is a triangle you have to divide it by 2
36/2=18
18
 
        
                    
             
        
        
        
2xy + 5x -12y -30
x(2y + 5)  - 6( 2y + 5)
(2y+5) (x-6)
