Because these triangles are congruent, then angle a is the same degree measure as angle x; angle b is the same as y; and angle c is the same as z. We also know that, because of the Triangle Angle-sum Theorem, all the angles of a triangle have to add up to equal 180 degrees. So for us that means that a+b+c(which is also z) = 180. 50 + 2x + 40 + 4x + 8 = 180. Combining like terms we have 6x + 98 = 180. Subbtracting 98 from both sides gives us 6x = 82 and x = 13 2/3
Answer:
30
Step-by-step explanation:
40-10=30 so N has to be 30

Answer:
Average annual tuition is $16991 for the year 2020.
Step-by-step explanation:
By using excel for the equation of the line of best fit,
Slope of the line from given data = 380.0286
y - intercept of the line = 11290.1
Therefore, equation of the regression line will be,
y = 380.0286x + 11290.1
Where x = number of years after 2005
Now we have to calculate the average annual tuition in the year 2020,
By substituting the value of x = 2020 - 2005
= 15 years
y = 380.0286×(15) + 11290.1
y = 16990.529
≈ 16991
Therefore, average annual tuition is $16991 for the year 2020.
First we write the expressions of each day separately:
Day 1:
you traveled x miles:
x
Day 2:
you drove 58 miles more than 3 times the thousands on Day 1:
3x + 58
Day 3:
your family went 25 fewer thousands than Day 1
x-25
Then, we have:
Day 1 + Day 2 + Day 3:
x + (3x + 58) + (x-25)
Rewriting:
x + 3x + x + 58 - 25
5x + 33
Then, for x = 100
5 * (100) + 33 = 533 miles.
answer:
5x + 33
Total miles that family traveled from home to Disney World is
533 miles
