In right triangle ABC with C =90°. If a=2.75ft , c=4.05ft, solve for all the missing parts
------
Draw the picture: a is opposite A ; b is opposite B ; c is opposite C
---------------------------
sin(A) = a/c = 2.75/4.05
A = arcsin(2.75/4.05) = 42.77 degrees
---------------------
B = C - 42.77 = 47.23 degrees
------
b = 4.05*cos(47.23) = 2.75
------------------
Cheers,
