Does anyone know how to find the measure of this missing angle ?

x=57

Step-by-step explanation:

x+28+x+38=180

Step 1: Simplify both sides of the equation.

x+28+x+38=180

(x+x)+(28+38)=180(Combine Like Terms)

2x+66=180

2x+66=180

Step 2: Subtract 66 from both sides.

2x+66−66=180−66

2x=114

Step 3: Divide both sides by 2.

2x/2=114/2

x=57

57

Step-by-step explanation:

x+28+x+38=180

2x+66=180

-66           -66

2x=114

/2    /2

x=57
