Question

find the acute angle
between the lines
x-2y+1=0, 2x+5y-5=0​

Answer 1

Answer:

Step-by-step explanation:The line x+2y=1 can be written as 2y= -x+1 or y = (-1/2)x+(1/2) = m1x + c1 …(1)

The line x-3y=5 can be written as 3y=x+5, or y = (1/3)x+(5/3) = m2x + c2 …(2)

The slope of Line 1 = -0.5 or -26.565 deg.

The slope of Line 2 = 1/3 or 18.435 deg.

So the angle between Line 1 and Line 2 = 18.435-(-26.565) = 45 deg.
