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.
Nitrogen (78%), Oxygen (21%), Argon (0.9%), and the remaining 0.1% consists of traces of neon, krypton xenon, carbon dioxide, nitrogen oxides, and traces of others. so Nitrogen is the greatest. I hope this helps :)
Answer:
A. 74
Explanation:
The given mortality rate is understood to be <em>deaths per thousand per year</em>. So, among 10 thousand people, one might expect 10×7.4 = 74 deaths per year.

Answer:
Alps mountains
Explanation:
The highest mountain ranges of Europe is the Alps mountain range. It is one of the most extensive mountain ranges system in the world. It stretches across eight alpine countries. They are France, Italy, Switzerland, Germany, Monaco, Slovenia, Liechtenstein and Austria.
It is formed around 65 million years ago due to the collision of the Eurasian tectonic plates and the African tectonic plates. It stretches in southeast direction from France through Switzerland and into Austria. Its elevation is about 6,000 feet.
