Given m<A and a: find b o.o?
I'm new to trig and I'm trying to figure out a problem but I'm stuck on the last step.
I know that A=45 degrees and a= 21
so I did the problems to this step:
b= a/tan A
so
b= 21/tan A
but what number do I divide 21 by to get the answer? whats the next step in finding the number I need to solve the problem? I am homeschooled and my teacher only listed up to that step she didnt show us how to solve it. I tried dividing 21 by 45, and also by the square root of 45 but none of the answers are listed. Please help me find the next step.
