Answer:

3.75

Step-by-step explanation:

Angle 2 and angle 3 are supplementary angles, so we can add them together and put it equal to 180°

Equation:

30x + 14 + 10x + 16 = 180

Combine like terms:

40x + 30 = 180

Subtract 30 from both sides:

40x = 150

Divide both sides by 40:

3.75

Check:

Take the orginal equation:

30x + 14 + 10x + 16 = 180

Plug in for x:

30(3.75) + 14 + 10(3.75) + 16 = 180

Solve:

112.5 + 14 + 37.5 + 16 = 180

180 = 180 ✅
