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.
Chinese traditional culture includes three systems of thought: Confucianism, Daoism and Buddhism.Chinese culture has developed into a system by uniting the three religions into one with Confucianism at the centre supported by Daoism and Buddhism
The electric distance meter and extensometer are used to measure length between two points and tensile strength respectively.
Electronic distance measurement uses electromagnetic waves such as infrared light while extensometer place the object under stress.
<h3>What is Electronic distance measurement and extensometer?</h3>
Electronic distance measurement and extensometer are tools that can be used to Know the length between two points and tensile strength respectively using different techniques.
The extensometer usually places a sample under stress to determine the length of the material while Electronic distance measurement uses beam of infrared light.
