1. the tan of 25
tan(25)=0.4663076582
now that rounded to the nearest ten thousandth
this mean to 4 decimal places
tan(25)=0.4663
for A.
we use tan^-1, or arctan
A= tan^-1(1.3270)= 52.99 degrees
A=52.99 or rounded A=53 degrees
B.
we find A in the same way, but we will use sin^-1
sin^-1(0.5373)=32.5 degrees
