Answer:
Step-by-step explanation:
The sum of angles in a triangle is 180°, so angle x is the complement of the one marked 31°. 
   x = 90 -31
   x = 59
__
The tangent relation tells you ...
   tan(31°) = 10/y
   y = 10/tan(31°) = 10/0.6009
   y ≈ 16.64
__
The sine relation tells you ...
   sin(31°) = 10/z
   z = 10/sin(31°) = 10/0.5150 
   z ≈ 19.42
 
        
             
        
        
        
Answer:
7m
Step-by-step explanation:
P=a+b+c+d
31=6+8+10+d
31=24+d
31-24=d
7=d
 
        
             
        
        
        
Total number of possible outcomes = 36
Total number of outcomes with sum 9 = 4
{3, 6} (4, 5) {5, 4} (6, 3}
P(Sum = 9) = 4/36 = 1/9
Answer: 1/9
        
             
        
        
        
Answer:
-6
Step-by-step explanation:
given 
x³ = -216
x = (-216)^⅓
factorize 
x = [(-6)×(-6)×(-6)]^⅓
x = -6
