### Example Question #1 : Finding Angles

What angle do the minute and hour hands of a clock form at 4:45?

**Possible Answers:**

**Correct answer:**

There are twelve numbers on a clock; from one to the next, a hand rotates . At 4:45, the minute hand is exactly on the "9" - that is, at the . The hour hand is three-fourths of the way from the "4" to the "5" - that is, on the position. Therefore, the difference is the angle they make:

### Example Question #2 : Finding Angles

What angle do the minute and hour hands of a clock form at 8:50?

**Possible Answers:**

**Correct answer:**

There are twelve numbers on a clock; from one to the next, a hand rotates . At 8:50, the minute hand is exactly on the "10" - that is, on the position. The hour hand is five-sixth of the way from the "8" to the "9" - that is, on the position. Therefore, the difference is the angle they make:

.

### Example Question #3 : Finding Angles

Note: Figure NOT drawn to scale.

The above hexagon is regular. What is ?

**Possible Answers:**

**Correct answer:**

Two of the angles of the quadrilateral formed are angles of a regular hexagon, so each measures

.

The four angles of the quadrilateral are . Their sum is , so we can set up, and solve for in, the equation:

### Example Question #1 : Finding Angles

Can a triangle have a set of angles that are and degrees?

**Possible Answers:**

No

Yes

**Correct answer:**

No

A triangle's angles must add up to degrees.

The angles given add up to 181,

.

That means that this cannot be an actual triangle.
