Find the length of are​

Answer 1

500 is the answering the sexagesimal

Answer 2

Answer:

Step-by-step explanation:

1)

1. 45°

We know , D/90 = G/100 =2C/π

Here, D = 15

So, 15/90 =G/100 =2C/π - ( 1 )

From ( 1 ),. G/100 = 15/90. And. 2C/π =

15/90

G =1/6×100 And. C=1/6×π/2

G = 50g/3. And C = π/12

15° = 50g/3 and. 15° = πc/12
