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.

how are the mississippi and amazon rivers differ? Check all that apply a- The Amazon acts as more of a barrier to movement b- Th

patriot [66]

Answer:

A-The Amazon acts as more of a barrier to movement

b- The Amazon is much harder to get to

c- The Amazon is surrounded by farmlands

Explanation:

The Amazon river has surroundings which are largely underdeveloped with large amount of plant life. They also inhabit lots of animal life too.The surroundings are hard to get to due to poor road network.

The Mississippi River however is found in a more developed industrial area and lacks a dense plant population with good road networks.

100 points! NO SPAM. I am researching the differences between Islam and ISIS, and also what they have in common. I need at least

Rzqust [24]

They are several similarities:

1) Most of the person in the Terror group "ISIS" follow "Islamic religion.
2) The people which follow both of them resides in west Asia like Afghanistan, Iraq, Syria etc.
3) ISIS have laws based on some misconcepts which are explainable by the religion "Islam"
4) They both believe in "Zihad" it is religious thing, whose goal is to achieve "Heaven in their language it is "Jannat"
5) They both are Organization, which means they both work under an organized law which is followed by everyone in their community.

The differences between them are:

1) Islam is the religion & ISIS is an organization.
2) Islam originated in 6 Century A.D. whereas ISIS originated like 60 Years ago.
3) Islam follow God, so most of their people believe in peace whereas ISIS is a terror group so they believe in harm others.
4) Islam can be followed by everyone and it is legal whereas ISIS is a bad thing & illegal.
5) ISIS has one leader name "Baghdadi" whereas Islam have their God name "Allah"
6) ISIS is limited in west Asia whereas a person who follow Islam can be found anywhere around the world

Hope this helps!
