Answer:
The missing angle is 24 degrees
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
x+156 = 180
Subtract 156 from each side
x+156-156 = 180- 156
x = 24
The missing angle is 24 degrees
 
        
             
        
        
        
Answer:
sin s = 36 / 42 = 18 / 21 = 6/ 7 
sin R = 14 / 42 = 7 / 21 = 1 / 3 
cos s = 14 / 42 = 1 / 3 
cos R = 36 / 42 = 6 / 7 
 
        
             
        
        
        
The answer would be 75 using the formula v=1/2(a)(c)(h)
        
                    
             
        
        
        
Answer:
tanΘ = - 
Step-by-step explanation:
Using the trigonometric identities
• sin²x + cos²x = 1, hence
cosx = ± √(1 - sin²x )
• tanx = 
given sinΘ =  , then
, then
cosΘ = ±  
Since Θ is in the second quadrant where cosΘ < 0, then
cosΘ = - 
          = -  = -
 = - 
tanΘ = 
         =  × -
 × -  = -
 = -
