Line AC is a tangent to the circle at point B. Line FB is parallel to line ED.

Line EF is the same length as line ED. Angle DBC = 38° Work out the size of angle FBD.

(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
