What is x? answer fast please!
Sindrei [870]

Answer:

\Huge \boxed{{x=15\°}}

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

We can create an equation.

x + 165 = 180

Solve for x.

Subtract 165 from both sides.

x + 165 - 165 = 180 - 165

Simplify the equation.

x = 15
