Answer:
yes
Step-by-step explanation:

We have a transversal across parallel lines so we get the usual array of congruent and supplementary angles. We just have to figure out which is which, and the diagram, even though not to scale, makes it pretty obvious.
Angle x isn't the same as the 40° angle so it must be its supplement.
Answer: C 140°
3.
r=1.2, h=2.9, V = (1/3) πr²h
Nothing hard here, we just plug in the numbers,
V = (1/3) π (1.2)² (2.9) ≈ 4.37310
Answer: B. 4.4 cubic inches
4.
Dilation by .5 makes a similar triangle, and reflection is an isomorphism (i.e. it doesn't change the size or shape) so the answer is
Answer: B similar not congruent
5.
The corresponding interior and exterior angles of a triangle form a linear pair, so supplementary angles. x=180-110 = 70°
Answer: A 70°

Answer:
The correct answer is the equation stands as 4x =40 where x is the number of pages Naomi would require and the value of this x is 10.
Step-by-step explanation:
Number of countries that competed in 1900 summer Olympic games is 28.
Number of countries that competed in 1904 summer Olympic games is 12.
Total number of countries competed in total is 40.
Each page of Naomi's report contains information about 4 of the countries that competed each year.
Let Naomi need x number of pages to incorporate the whole report.
Thus the equation now stands as 4 × x = 40.
⇒ x = 10.
Thus Naomi would require 10 pages to complete her report.
Answer:
x = 3
Step-by-step explanation:
The smaller triangle and larger one are similar, so corresponding sides are proportional.
8/4 = (8 +(x -1))/5
10 = x +7 . . . . . . . . . multiply by 5 and simplify
3 = x . . . . . . . . . subtract 7

<em>Alternate solution</em>
The short segments are also proportional:
(x -1)/(5 -4) = 8/4
x -1 = 2 . . . . simplify
x = 3 . . . . . . add 1
