So here’s a example and formula
Answer:
using the pythagoras theorem the answer is a=3
Step-by-step explanation:
basically in a right angled triangle a² + b² equals c². in this equation c is the number on the hypotenuse (the line opposite the right angle)
and 4 could be a or b it doesnt make a difference so I'll call it b.
because we have c² and b² we work backwards like this:


because 9 is a², we must find the square root to find <em>a</em>

so a equals 3
Write an Expression:
4.25*9 = X
4.25*9 = 38.25 in²
