Answer:
Step-by-step explanation:
I'm answering because I could use the points, but the answer is correct. For a full explanation, see the other posted question. :D
TSP makes a right triangle with TS and TP being the sides and SP being the hypotenuse.
Using the Pythagorean theorem and the two given sides you can solve for the hypotenuse.
SP = √6^2 + 8^2
SP = √36+64
SP = √100
SP = 10 cm.
Since the value of the y-coordinates are the same for both points, the distance between the lines is the difference in x-coordinates, namely
distance = xh-xg = -12 - (-4) = -8, or 8 units in absolute value.
