Answer:

1/2

Step-by-step explanation:

When two lines whose scopes are m₁ and m₂ are perpendicular, then the product of the scopes of both lines is -1.

Therefore,

If m₁ is the scope of line a and m₂ is the scope of line b then,

m₁m₂ = -1 and m₁ = -2

-2m₂ = -1

m₂ = -1/-2 = 1/2

The slope of line b is 1/2.

Step-by-step explanation:

12 22.5  X

Let X be the shortest distance we are trying to find.

a units 2 b units 2 c units 2

12 units 2 + (22.5)=c units 2

144+506.25=c units 2

650.25=c units 2

\sqrt{x} 650.25=c units 2

Answer:

x=4.8

This here you use Pythagorean Theorem.

Step-by-step explanation:

a^2+b^2=c^2

The longest side is c. And the two legs are a and b.

So it'd be 11^2+x^2=12^2

121+x^2=144

Subtract 121 from both sides.

x^2=23

Then take the √ of x^2 and 23

So √x^2=√23

x=4.8

Hope this helps
