V=B+15
V+2B=180
Therefore:
3B+15=180
B=55
V=70
Check:
V+2B=180
70+2(55)=180
70+110=180
180=180. Checks.

The way to answer this question is to first make 52% into a decimal:
52% = 0.52
so now we will simply multiply:
   84
x.52
once you have multiplied these numbers it comes out to be 43.68.
So your answer is 43.68.
Hope this answer helps! feel free to ask any additional questions :)
        
             
        
        
        
Based off of  what I can see in the  photo (its too blurry to know for sure) and what I think you're asking:
The angle of a triangle always adds up to 360degrees, so base it on that and the acute and obtuse  angles  and get the degrees from there, the angle would be those degrees you find or <10, 5, 4 (what I assume  is a 5)
