Answer:
70°
Step-by-step explanation:
The minor angle of AB forms a straight line with angle x. When summed up it equals 180°.
minor angle of AB + x° = 180°
110° + x° = 180°
x° = 180° - 110°
= 70°

Answer:
12 2/3
Step-by-step explanation:
I'm too lazy to give an explanation. Hope this helped though.
L1: 2x+4y-3=0 ..........(1)
P: (2,0)
The point on the line L1 closest to the given point P is at the intersection of L1 with L2, which is the perpendicular passing through P.
Slope of L1=-2/4=-1/2
Slope of L2=-1/(-1/2)=2
Since it passes throug P(2,0), we can use the point-slope formula:
(y-0)=2(x-2) =>
L2: 2x-y-4=0.............(2)
Solve for x & y using (1) and (2) to get intersection point required:
(1)-(2)
2x-2x + 4y-(-y) -3 -(-4) =0
5y=-1, y=-1/5
Substitute y=1/5 in equation (1)
2x+4(-1/5)-3=0 =>
2x-19/5=0
x=19/10
=> the point on L1 closest to (2,0) is (19/10, -1/5)
The x-intercept is when y=0, so we plug that in our equation,
. +12 on both sides to get
. Divide by -8 to get
