Answer:
33
Step-by-step explanation:
4,14,24,34,40,41,42,43,44,45,46,47,48,49,54,64,74,84,94,
104,114,124,134,140,141,142,143,144,145,146,147,148,149
let each angle=A
A+A+A=180
3A=180
A=180/3=60°
as the angles are equal so sides are equal.
16+y=46
y=46-16=30
applying sine formula
z+x=60
40+x=60
x=60-40=20°
49
64- 15 = 49
Hope that this helps you and have a great day
