Let the measure of the second angle be x.
The first angle has measure 3x - 34.
The sum of the measures is 180.

x + 3x - 34 = 180

4x - 34 = 180

4x = 214

x = 53.5

The second angle has measure 53.5 deg.

3x - 34 = 3 * 53.5 - 34 = 160.5 - 34 = 126.5

The measure of the first angle is 126.5 deg.

Answer: The measures are 126.5 deg and 53.5 deg.

A programmer wants to display how the shape of a rectangle with a fixed perimeter of 300 inches can be changed by varying the re
stiv31 [10]

If the rectangle has a fixed width of 300, it means that

2(l+w)=300 \iff l+w=150 \iff w=150-l

where w and l are width and length, respetively.

So given the length l, the are would be

l\times w = l\times (150-l)=-l^2+150l

The graph below shows the time Andrea spent reading one day. Write a few sentences to describe the relationship between the time
Alex777 [14]

Answer:

Step-by-step explanation:

Well, there are several  relationships you can describe.  As time increases how does number of pages  react?  Like does it increase or decrease.  Is it always increasing or decreasing by the same amount?  If it's not all the same how do different parts look different.  

There aren't any actual numbers, so you can't say specifically how they relate, like you can't say she read 5 pages a minute or something.

How can i find the midpoint of a line segment ?​
eimsori [14]

Answer:

add both x coordinates and divide them by 2.

add both y coordinates and divide them by 2.

Now final product should be (x,y)

Step-by-step explanation:

Example.

let's take 2 points:

(2,5) and (7, 9)

let's add both x coordinates.

2+7 = 9

now add both y coordinates.

5+9 = 14

Now divide both by 2.

Final answer should be (4.5, 7) = this is your midpoint
