Question

estimate the measure of ∠fgh to the nearest 10°. answer attempt 1 out of 3

Explanation:

Step1: Visual - estimate angle

By looking at the angle $\angle FGH$, it appears to be an obtuse angle. It is clearly more than $90^{\circ}$ but less than $180^{\circ}$. A rough visual - inspection shows it is around $120^{\circ}$.

Step2: Round to nearest 10°

Since $120^{\circ}$ is already a multiple of $10^{\circ}$, no further rounding is needed.

Answer:

$120^{\circ}$
