Given: angle = 25°, hypotenuse = 100, opposite = ???


The answer is 16, you substitute the value of the variable into the equation and simplify
X equals 60 because 2x60=120. and 120-10=110
Use substitution
Set them equal to each other
-3x + 4 = 3x - 2
Solve the equation
4 = 6x - 2
6x = 6, x = 1
Plug in 1 for any equation to find y
Y = -3(1) + 4
Y = -3 + 4, y = 1
Solution: x = 1, y = 1
