Find the following angle measures of angle EAD and angle CAB
Dominik [7]

Answer:

m<EAD=29°

m<CAB=119°

Step-by-step explanation:

Angles on a straight line sum up to 180°

This implies that,

61°+90°+EAD=180°

151°+EAD=180°

Subtracting 151° from both sides,we obtain,

EAD=180°-151°

EAD=29°

Angles on a straight line add up to 180°.

This implies that,

CAB+61°=180°

Subtracting 61° from both sides,we obtain

CAB=180°-61°

CAB=119°

Thus,m<EAD=29° and m<CAB=119°
