Question

if theta is the acute angle between the lines x+y-5=0 and 2x-y-10=0 then find the value of tan theta​

Answer 1

Answer:

we know that slope is given by tan function

first soope of line 1 = -A/B= -1= m1

m2= 2

acute angle = tan● = mode of m1-m2/1-m1m2

here we get two values of tan● use smaller for acute other is for obtuse

okay
