Use a^2 + b^2 = c^2
the triangle must be isosceles because the two angles are the same
1.2^2 + 1.2^2 = x^2 
1.44 + 1.44 = x^2
2.88 = x^2
x=6√2/5
or
x ≈1.69706
        
             
        
        
        

Explanation:
The triangle is right angled.
The formula for area of the triangle:

base = 3
height = 4
substitute the values:
 
 
        
             
        
        
        
Kevin would have to write 133 problems, as 14/5= $2.8 per problem 370/2.8= 132.14 but since he can’t be paid to write .14 of a problem he needs to finish it making the answer 133 problems
