Solving problems using angle relationships

What kind of angle is this? What is it's measure

• acute, 90

• right, 180

• obtuse, 180

• right, 90

Find the value of the variable

• y=20

• y=90

• y=70

• y=110

What is true about these vertical angles?

7t = 35; solve for t

• t = 7

• t = 90

• t = 65

• t = 5

Which two angles are supplementary?

There are two correct answers.

Solve for b.

• b = 180

• b = 112

• b = 68

• b = 90

Solve for x.

• x = 60

• x = 90

• x = 40

• x = 180

2k + 110 = ?

• 180

• 55

• 90

• 220

Solve for k

• k = 180

• k = 110

• k = 35

• k = 55

Solve for d.

These are vertical angles!

• d = 50

• d = 60

• d = 90

• d = 180
