Question

estimate the measure of ∠bcd to the nearest 10°. answer attempt 1 out of 2

Explanation:

Step1: Visual - estimate angle

By looking at the angle $\angle BCD$, it appears to be around $60^{\circ}$. Since we need to estimate to the nearest $10^{\circ}$, and $60^{\circ}$ is already a multiple of $10^{\circ}$.

Answer:

$60^{\circ}$
