There are two triangles. One has a base of 8cm and the height of 10 cm the other has a base of 5cm and a height of 13cm which tr

So the first thing you want to do is look at the exterior angle 130°. A straight line is 180°, and every Triangle's angular sum is 180°. How I think of it is that every straight line has a mini protractor on either side. It makes it a bit easier to understand.
180 - 130 = 50
You now know that two of the angles are 50°.
You now have two of the measurements for the triangle farthest to the left.
75° and 50°
75 + 50 = 125
180 - 125 = 55
a = 55°
Now that you have all the measurements for the first triangle, let's move onto the next one.
With two measurements for the second triangle, all you need to do is find their sum and subtract that from 180 and you will have the third measurement!
50 + 60 = 110
180 - 110 = 70
b = 70°
Finally, for the last triangle, you already have two of the measurements 60° and 85°.
85 + 60 = 145
180 - 145 = 35
c = 35°
Sorry if this explanation is a bit messy, it's hard to describe certain things without a letter or some kind of name to differentiate between them verbally.
I hope this helps! <3
Answer:
A.
B. 42.2 million
Step-by-step explanation:
Part A:
Given:
Newspapers circulated in year 2004,
Newspapers circulated in year 2014,
Let the time start at the year 2004. So,
For the year 2014,
Therefore, linear relationship between newspapers circulated and time passed since 2004 is given as:
Therefore, the equation describing the relationship is:
Part B:
For the year 2018,
Plug in 14 for in the above equation and solve for
. This gives,
Therefore, in the year 2018, the newspaper circulation will be 42.2 million.
a = 2x + 6xz
a = x(2 + 6z) <em>factored out "x" on right side</em>
a/(2 + 6z) = x <em>divided both sides by (2 + 6z)</em>
Answer: x =
