Question

finding angles measures
find the following angle measures.
m∠ead =

m∠cab =

Explanation:

Step1: Analyze $\angle EAD$

Since $\angle EAF = 90^{\circ}$ and $\angle DAF=61^{\circ}$, then $m\angle EAD=m\angle EAF - m\angle DAF$. So $m\angle EAD = 90^{\circ}-61^{\circ}=29^{\circ}$.

Step2: Analyze $\angle CAB$

$\angle CAB$ is a straight - angle. By the definition of a straight - angle, its measure is $180^{\circ}$.

Answer:

$m\angle EAD = 29^{\circ}$
$m\angle CAB=180^{\circ}$
