Question 167754
A which is 29 degrees, 
side CA of 18 meters, 
and a right angle which is angle C.
--------------------------------------- 

Here's what I found out so far:
that angle b = 61 degrees
but I do not know how to figure out CB and BA
--------------------
Draw the picture.
CB is opposite angle A=29 degrees.
BA is opposite angle C so BA is the hypotenuse
CA is opposite angle B
----------------------
So, cos(A) = adjacent/hypotenuse
cos(29) = 18/hypotenuse
hypotenuse = 18/cos(29) = 20.58
-----------------------------------
sin(A) = CB/hypotenuse
CB = hypotenuse*sin(A)
CB = 20.58*0.4848..
CB = 9.97738....
