There are 180 degrees in a triangle
4. 38+38= 76 degrees 
180-76=104
Isosceles, Obtuse 
5. 65+ x+x=65
Well we know one of the x
It is 90 degrees because it is a right angle
65+90=155
180-155=25
Scalene, Right triangle
6. 71+45= 116
180-116=64 
7.  Scalene, acute
8. 126+22=148
180-148=32
Scalene, Obtuse
9. 50+90=140
180-140=40
Right angle,  Scalene

Given parameters: 
Current population  = 530,300 people
Growth rate  = 0.8% per year
Unknown
Population in 15 more years  = ? 
To solve this problem, we  must compound the increase per year. 
This implies that we treat the problem like that of a compound interest. 
Since we know that population increases by 0.8%,
                           it is similar to 1 +  = 1.008 increase
  = 1.008 increase
Now the population in 15years will be; 
                 530300 x (1.008)¹⁵  = 597626 people
So, the population after 15yrs is 597626 people
 
        
             
        
        
        
It's the one on the top righr, -2/9 w + 2/15.
