Answer:
Step-by-step explanation:
The given trapezoid is an isosceles trapezoid, meaning that the two legs of the trapezoid (sides that intersect the parallel lines) are congruent. One of the proprieties of an isosceles trapezoid is that the opposite angles are supplementary, meaning that the sum of the opposite angles is 180. One can apply this theorem here by stating the following,
Substitute,

Answer:
The light blue one -- second from the left.
x = 14 ; y = 7√2
Step-by-step explanation:
This is a right triangle. One of the angles is 45. So is the other base angle.
So one of the legs is 7√2. The other leg is also 7√2 because they are opposite equal angles.
The hypotenuse is
a^2 + b^2 = c^2
a = b
2a^2 = c^2
2 (7√2)² = c^2
2 49 * 2 = c^2
4 * 49 = c^2
c^2 = 196
c = 14

Answer:
-6+x
Step-by-step explanation:
Let the number=n
x-n=6
-n=6-x
n=-6+x
Answer:
y = 3
x = -4
Step-by-step explanation:
Hopefully the first equation is x + 3y = 5
x = 5 - 3y
Plug in:
-2(5 - 3y) + 2y = 14
-10 + 6y + 2y = 14
8y = 24
y = 3
x = -4
