Technically, none of the equations.
The equation you're looking for would be:
x²+(x+20)²=150²
Answer:
4
Step-by-step explanation:
13497/1250
12500 + 997/1250
12500 + 0.7976
12500.7976
Let, the number = x
It would be: x * 96% = 42
x * 0.96 = 42
x = 42 / 0.96
x = 43.75
In short, Your Answer would be 43.75
Hope this helps!
