## Geometry: Common Core (15th Edition)

A clock has 12 sections. A clock is a circle, and circles have 360 degrees, so each section is 360/12=30 degrees. At 7:00, the minute hand is at 12 and the hour hand is at 7, so there are exactly 5 sections. Multiply the degrees per section (30) by the number of sections (5) to obtain $30*5=150$.
