Answer 1

Step-by-step explanation:

A)

1)m(arc EF)=70°

2)m(arc DE)+m(arc EF)+m(arc DGF)=360°

m(arc DE)+70°+200°=360°

m(arc DE)=360°-270°

3)m(arc DE)=90°

m(arc DEF)=m(arc DE)+m(arc EF)

=90°+70°

4)m(arc DEF)=160°

B)

1)Angle BCA=60°

2) BC=(1/2)AC. and. AB=(√3/2)AC

3)BC=(1/2)*14

BC=7

C)

1)angle APB=90°

2)angle AQC=90°

3)angle PAB ~= angle QAC. (equal angles)

4)∆APB~∆AQC. AAA test (angle angle angle test)
