match the correct equation to solve each problem:

• x = 1/2 (32 + 54)

• 
• x = 1/2 (90 + 200)

• 
• 42 = 1/2 (x - 68)

• 
• 2x + (2x + 4) = 180

• 
• x = 1/2 (125 - 27)

•

match the equations to solve each problem

• angle = 1/2 ((360-112) - 112)

• 
• 112 + x = 180

• 
• 2x^2 + 4 = 22

• 
• P = 2(7 + 4 + 10)

• 
• 2x + 16 + x = 180
