Answer 2

Step-by-step explanation:

1. Given: angleA=44°,(1)

AB=AC, so angleB=angleC---(2)

[Angles opposite to the equal sides are equal]

A°+B°+C°=180°[ Angle sum property]

44°+B°+C°=180°[from (1)]

44°+B°+B°=180°[from (2)]

2B°=180°-44°=136°

B°=136°/2=68°.

Hence, angleB=angleC=68°.

2. Given: angleR=42°----,(1)

PQ=PR, so angleP=angleQ---(2)

[Angles opposite to the equal sides are equal]

P°+Q°+R°=180°[ Angle sum property]

42°+P°+Q°=180°[from (1)]

44°+P°+P°=180°[from (2)]

2P°=180°-42°=138°

P°=138°/2=69°.

Hence, angleP=angleQ=69°.
