If vertex angle is 42, and the base angles are congruent, this is an isosceles triangle, they each measure: 180-42/2. They each measure 69 degrees. The length of sides don't matter.
        
                    
             
        
        
        
Answer:
25
Step-by-step explanation:
By counting the height ( frequency ) of each block and adding gives the number of students in total
20 - 24 → 5
24 - 28 → 6
28 - 32 → 5
32 - 36 → 2
36 - 40 → 7
Total = 5 + 6 + 5 + 2 + 7 = 25

Answer:
36000pi
Step-by-step explanation:
V = 4/3*pi*r^3  so we need to know r
we know surface area, which is 4pi*r^2=3600pi.  so we can solve for r
r=30
so v = 4/3*pi*30^3 = 36000pi
 
        
             
        
        
        
3*3*3=9 perhaps?? And then it would be in Surface Area??
