Tan a=-(-5/12) cos b=-1/3
tan=o/a cos=a/h
both have quadrant 3,using q3,
draw triangle to find out that hypothenous is square root of 8,
reuse formula tan=o/a,
tan b=square root of 8/1
so the answer is square root of 8
1 5 1
Is it necessary to simplify the final answer?
what means?like decimal place?
no need just haha sorry my keyboard have no square root symbol,just write square root of 8 if the question no mention about decimal place
okay, thank you for your help
