Step-by-step explanation:
vertical angles congrunet (angleFJH + angle GJI) 
& (angleHFJ + angle JGI congruent)
 
        
             
        
        
        
Answer:
a. 60/61
Step-by-step explanation:
With reference angle A
base(b) = 60
hypotenuse (h) = 61
Now
Cos(A) = b / h
 = 60/ 61

Area=1/2 times base times height
for equilateral triangle, if base is x, then height is (x√3)/2
so if base is 6 then height is (6√3)/2=3√3
area is 1/2 times 6 times3√3=3 times 3√3=9√3 sqare inches
        
             
        
        
        
Answer:
Step-by-step explanation:
subtract 6-5.5 to get .5
and then divide .5/6 to get 0.0833
then multiply that quotient by 100 to get percentage
8.33% or 8.3% if you go to the nearest tenth
