1

Solve for x.

52degrees

$38^\circ$

$36^\circ$

$34^\circ$

$32^\circ$

$30^\circ$

Explanation

To solve for x we subtract.

2

Solve for x.

180 degrees

$90^\circ$

$80^\circ$

$100^\circ$

$85^\circ$

$95^\circ$

Explanation

The angle is a straight line. A straight line is $180^\circ$ . To find the missing angle we subtract.

3

Solve for x.

45degrees

$45^\circ$

$40^\circ$

$50^\circ$

$35^\circ$

$30^\circ$

Explanation

Because of the square in the corner of the angle we have a $90^\circ$ angle. To find the missing piece of the angle we subtract.

4

Solve for x.

100degrees

$100^\circ$

$110^\circ$

$120^\circ$

$130^\circ$

$140^\circ$

Explanation

To find the value of x we add both of the known angles together.

5

If we wanted to make this angle into a right angle, how many more degrees would we need to add?

27degrees

$63^\circ$

$64^\circ$

$65^\circ$

$66^\circ$

$67^\circ$

Explanation

A right angle has a measurement of $90^\circ$ . To find how much more we would need to add we subtract.
