Answer:
I think the right method to protect the environment and protect energy is to use renewable resources. If we used renewable resources within time all the nonrenewable resources we used would be replenished. I also think this would be the right thing to do because, for example if we used solar or wind energy we wouldn't waste energy as much as we do now days.
However if we were to use this. The cost for using renewable energy would be money. These days solar energy is very expensive, if we were to start using it we would spend a lot of money. Another thing is we would have to make sure that we are storing some energy in case the weather conditions are bad. (solar energy)
All in all, I think using renewable energy is the way to go, if we used this we could protect the environment.

I got it from a Quizizz I think your teacher might of got some questions from there if you want the link just comment and I'll give it to you
Below I have included an image that has the measure of all of the angles on it.
We can find the measures of the angles here due to the laws about complimentary angles. A pair of complimentary angles can be formed when 2 lines are perpendicular, and when added together, will always equal 90. The pair are the angles that are not directly adjacent from each other. In this figure, "x" and "(4x-10)" are a pair. According to another law, opposite angles, or adjacent angles, will always be equal to each other. Using the logic above is how we can find the measure of all angles.
Since one angle has a box, we know the lines are perpendicular, and that the laws of complimentary angles apply. We can also use that to see that the angle diagonal from it is equal to 90.
To solve for the other measures, we need to add the 2 equations together and set them equal to 90 (because of that law we talked about before).
x+(4x-10)=90
5x-10=90
+10+10
5x=100
/5 /5
x=20
Now that we know x equals 20, we can substitute that value in and solve.
x=20
=(4x-10)
=(4*20-10)
=(80-10)
=70
We also know this is correct because 20 and 70 equal 90.
