The measure of two angles are (5x + 10) and (9x - 14).  What is the value of x if these angles are congruent?

• x =  1

• x = 6

• x = -1

• x = -6

Find the values of x and y.

• x=7 ; y=25

• x=5 ; y=25

• x=7 ; y=5

• x=5; y=5

Find the values of y and z.

• y=76, z=114

• y=104, z=76

• y=76, z=104

• z=114, y=76

• 32

• 23.1

• 28

• 16.9

• 2x-6=7x+4
• 2x-6+7x+4=90
• 2x-6+7x+4=180
• 2x-6+7x+4=360

Look at the diagram.
