Question

find the measure of angle bdc. * 1 point

Explanation:

Step1: Identify angle - type relationship

We know that $\angle ADC = 90^{\circ}$ and $\angle ADB=49^{\circ}$.

Step2: Use angle - subtraction formula

$\angle BDC=\angle ADC-\angle ADB$.

Step3: Substitute values

$\angle BDC = 90^{\circ}-49^{\circ}$.

Step4: Calculate result

$\angle BDC = 41^{\circ}$.

Answer:

$41^{\circ}$
