Question

in the figure, m (arc NS) = 1300
(arc EF) = 60°. Find
EL
(1) Z NMS
(ii) Z ENF
ii) Z NFS
F​

Answer 1

Answer:

1) 70°

2) 45°

3) 65°

Step-by-step explanation:

1) NMS = m(arc NS) - m(arc EF)

= 130 - 60

= 70°

2) 2 ENF = m (arc EF)

ENF = 70÷2

= 45°

3) 2 NFS = m (arc NS)

NFS = 130/2

= 65°
