Find the acute angle between each of the following pairs of straight lines:
with gradient 3 and 3/4
* I know how to solve these when one of the grandients are a negative number...except this time, their both positive and I keep on getting the wrong answer
AND when solving for the acute angle of a negative gradiented line, II get
tan(pheta)=-m
pheta=180-(tan-1(-m))
how come i keep getting the wrong answer???
which part of my step is wrong??
