The correct answer is 1/8.
angle 4 is the same as angle 8
angle 7 & angle 8 has to equal 180 degree
so angle 7 and angle 4 also have to equal 180
angle 4 is 3 times the size of 7
lets call 7 (x)
so 4(x) = 180
180/4 =45
x=45
angle 7 is 45 degrees
It is 2. You flip the fraction and make it negative always to get perpendicular slopes. If it was like 3, you treat it as 3/1 and would make it -1/3.
