Answer:
3.9 broo
Step-by-step explanation:
Bro use the Sin law
a / Sin A = b / sin B = c / sin C
the missing angle is 180 - (90 + 63) which is 27
so you have one side measure =>
-------------------------------------------------------------------
2 / sin 27 is equal to x / sin 63 solve to proportion, sooo
4.40537853 is equal to x/0.891006524
then: 4.40537853 times 0.891006524 is x
x = 3.92522101
so last choice, 3.9
