I am a 2-digit number greater than 50. One of my factors is 8 and I, myself, am a factor of 360. The
difference between my digits is 5.
What number am I?

72

Step-by-step explanation: greater than 50 ( 8x9=72 ) And 72 is a factor of 360, difference between my digits is 5 (72x5=360)

(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

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
