Question

1. what is the measure of the arc represented by the numbers 7 and 4 on a clock face? 90° 80° 60° 120°

Explanation:

Step1: Calculate degrees per clock number

A clock is a circle ($360^\circ$) with 12 numbers. Degrees per number: $\frac{360^\circ}{12} = 30^\circ$.

Step2: Find number of intervals between 7 and 4

Count intervals: 7→6→5→4 is 3 intervals.

Step3: Compute arc measure

Arc measure = $3 \times 30^\circ = 90^\circ$.

Answer:

90°
