Answer for first picture:

#1 = 43 degrees #2= 38 degrees

#3= 27 degrees #4= 45 degrees

Explanation for first picture:

All the angles are right angles. This means they all will equal 90 degrees! so if you take 90 degrees and subtract the one known angle you will have your answer! :)

Answer for 2nd picture:

#1 = X= 70 Y= 110

#2 = X= 102 Z= 102

#3 = X= 83 Y= 194

#4 = Y= 37 Z= 143

Explanation for second picture:

When you have angles like these the total will equal 360 degrees! look at the first pic, it shows 110 degrees, you also know that the angle across of it is equal to it. so together it equals 220 now subtract 360 - 220. you get 140. since you have two angles to figure out, you divide 140 into two. 140 / 2 = 70 degrees! you do the same steps for the rest of the problems!

( i am sorry for the bad explaining!)

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
