8.13in

Step-by-step explanation:

ok so the equation for length of an arc is given by 2πr(Ф/360). So we'll find out the remaining angle in the circle which would be 360-(150+65+73)=72°.

∴ Ф=72°. Now its just calculation.

so arc would be 2*3.14*6.48*(72/360)=40.69*0.2=8.13in

3201

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
