Answer:
See below
Step-by-step explanation:
Here is one way .... I showed you how to use Law of cosines in another Q
use this to find CB
CB^2 = 13^2 + 21^2 - 2(13)(21) cos 91 <==== solve for CB
THEN use law of SINES to find angle B
sin B / 21 = sin 91 / CB (CB you found using law of cosines above)
Well, 30-60 days shopping for a house, 14-60 days from contract to close, and 14-45 days or so before your first mortgage payment is due, it can be really quick and take as little as 30 days total, and sometimes the shopping period alone and last months and months
Hope this helps! :)
