We can use the vertical angle theorem which states that any two opposite angles are congruent. So, you can just set the two measures equal to each other and solve for x:
$7x-99=2x+1$
$5x-99=1$
$5x=100$
$x = \frac{100}{5} = 20$

So, your answer is 20°.

#1- Jennifer made a box plot to summarize this data. 124, 118, 129, 139, 133, 129, 142, 135, 122, 137. What is the median, the l

svp [43]

Answer:

B or

Lower quartile: 124

Median: 131

Upper quartile: 137

Step-by-step explanation:

To find the median first make the data in order from greatest to least:

118,122,124,129,129,133,135,137,139,142

Then find the middle 2 numbers which are 129 and 133

129+133=262 (divide by 2 to find average) so

median= 262/2=131

To find the Lower quartile find the number in the middle of the first 5 numbers which is 124

To find the Upper quartile find the number in the middle of the second 5 numbers which is 137 so

B or

Lower quartile: 124

Median: 131

Upper quartile: 137

Answer:

see the procedure

Step-by-step explanation:

Identify

Let

x ---> the cost of the Xbox one at Walmart

Strategy

we know that

The cost of the Xbox one at Walmart multiplied by 2 plus $50 must be equal to $450

Set up

The algebraic expression that represent this situation is

$450=2x+50$

Solve

solve for x

$450=2x+50$

$2x=450-50\\2x=400\\x=\$200$

Check

substitute the value of x in the equation

$450=2(200)+50$

$450=450$ ----> is ok

Help me answer this question :((((

Step-by-step explanation:

I cannot give an exact result but I will try.

What it means by this is to continue the graph up to 2010.

Based on its trajectory, you would simply draw the line on.

If I made a prediction on what it would end up on in 2010, I would say 50 percent.

The base of a 15-foot ladder is 6 feet from a building. If the ladder reaches the flat roof, how tall is the building?

Vlad [161]

Answer:

the answer would be 13.75 feet

Step-by-step explanation:

The computation of the tall is the building as follows:

Given that

Base is 6 foot

And, the hypotheses is 15 feet

Here we use the Pythagoras theorem

= √15^2 - √6^2

= √225 - √36

= √189

= 13.75 feet

Hence the answer would be 13.75 feet
