Short Answer

Expert verified

The angle $∠ C D B$ appears to be acute angle and it’s estimated measure is $m ∠ 6$ .

Step by step solution

Step 1. Apply the definition of acute angle.

Acute angle is an angle which measures between $0 °$ to $90 °$ .

Step 2. Description of step

From the given figure, it can be observed that the $∠ C D B$ measures between $0 °$ to $90 °$ therefore, $∠ C D B$ appears to be acute angle.

Step 3. Estimate the measure of ∠CDB

$∠ C D B = m ∠ 6$
