Answer:
angleB = 41.4°
Step-by-step explanation:
✨ Trigonometry✨
cos theta = adj / hyp
theta = inverse-cos adj / hyp
theta = inverse-cos 12 / 16
theta = inverse-cos .75
theta = 41.4°
*theta is the 0 with a line through it
 
        
             
        
        
        
8/1 + (x-1)/(x+4) 
You need the same common denominator (bottom number) to be able to add together so multiply 8 by (x+4) to both bottom and top 
8 (x+4)/(x+4) + (x-1)/(x+4)
Add 
8 (x+4)+(x-1)/ (x+4)
Distribute the 8 to (x+4)
8x+32+x-1 / x+4
Simplify 
9x+31/x+4
