Given:
A figure in which a transversal line intersect two parallel lines.
and 
.
To find:
The value of x and y.
Solution:
We know that, if a transversal line intersect two parallel lines, then
(1) Alternate exterior angles are equal.
(2) Same sided interior angles are supplementary. So their sum is 180 degrees.
In the given figure j and k are parallel lines and l is a transversal line.
From the given figure, it is clear that,
(Alternate exterior angles are equal)
Therefore, the value of x is 20.
Now,
(Same sided interior angles are supplementary)
Therefore, the value of y is 38.
Answer:
Step-by-step explanation:
3a-2b=14 multiply by 3
9a - 6b = 42 (1)
4a+3b=13 multiply by 2
8a +6b = 26 (2)
sum up (1) and (2)
17a = 68
a =4
b=-1
I just took the test, the answer is: Fiona's meals are less expensive. :)
Answer:
13/21
Step-by-step explanation:
Make 6 1/2 and 10 1/2 and improper fraction
6 1/2=13/2
10 1/2=21/2
K.C.F
Keep 13/2
Change the division symbol to multiplication
Flip 21/2 to 2/21
then multiply across
13*2=26
21*2=42
so the fraction is 26/42 and then simplify the fraction
13/21
Because these are opposite and they both have complimentary angles, you can set them equal to each other and solve for x
