Answer:

The lines are not perpendicular

Step-by-step explanation:

m1=1/2

m1*m2=1/2*2=1

Lines are perpendicular when m1 * m2 = -1 because m1 * m2 = 1 these lines are not perpendicular

3 feet

Step-by-step explanation:

A 12-foot ladder is leaning across a fence and is touching a higher wall located 3 feet behind the fence. The ladder makes an angle of 60 degrees with the ground.

ladder is 12 foot

The ladder makes an angle of 60 degrees with the ground.

It form a right angle triangle . ladder is the hypotenuse

$cos(60)=\frac{x}{12}$

$0.5= \frac{x}{12}$

multiply 12 on both sides

x= 6

the distance from the base of the ladder to the bottom of the fence

x-3 = 6-3=3 feet
