She had 22 friends at her graduation party.
Step-by-step explanation:
70 chocolates total minus 3 chocolates times the number of friends she had at the party = 4
70-3x=4

Divide both sides of the equation by -3
-3x/-3=-66/-3
Simplify
x=22

mathematically it is stated as

Given that
c, hypotenuse= 17 ft
a = 15 ft
b= ?
