(10 points) when given the m∠1 =(2x - 9) and m∠2 = (5x - 7),find the value of x that will make m || n?

For this one, set bot angles equal to 180 like this:  

2x-9+5x-7=180

The reasoning is a straight line has an angle of 180 and the two angles being in opposite positions, you can set them equal to 180.

Now combine like terms:

2x+5x=7x

-9-7=-16

Now your new problem looks like:

7x-16=180

Next isolate the x:

7x-16+16=180+16

7x=196

Now divide by 7 to make the x by itself:

7x/7=196/7

This comes out even to x=28.

Now since it is a word problem, higher math says to answer it in the same format:

To make m and n congruent, x has to equal 28.

Hope this helps!

sorry not sure

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
