Let the full marks be represented by = x
As given, 80% of x is 75
So,

x= 
x=93.75
Hence, full marks is 93.75
We can check also-
=75

Answer:
y = 8√3
Step-by-step explanation:
In the 30°-60°-90° "special" triangle, the ratio of sides lengths is ...
1 : √3 : 2 = 8 : y : hypotenuse
In order for these ratios to be equal, we must have ...
y = 8√3
__
If you want to solve this using your trig skills, you recognize that ...
Tan = Opposite/Adjacent
tan(30°) = 8/y
y = 8/tan(30°) . . . . where tan(30°) = 1/√3
y = 8√3
1 3/4 is greater than 0.75 because 1 3/4 is 1.75 and it is greater than 0.75
Is this math? I'm sorry I don't get what formula I'm supposed to rewrite or -
