In this figure, AB || CD and m/2= 60°.<br> What is mZ6?
liubo4ka [24]

Answer:

The measure of \angle 6\ is\ 60\°.

Step-by-step explanation:

Given,

AB║CD  and

m∠2 = 60°

Solution,

Since, in the figure given in attachment line segment AB is parallel to line segment CD. And t is the transversal line.

The theorem of parallel lines states that,

"If two lines are parallel and cut by a transversal line then the pair of corresponding angles are congruent."

So according to the theorem of parallel lines,∠2 and ∠6 makes a pair of corresponding angle.

And the measure of corresponding angle is equal.

So, m∠2 = m∠6

\therefore m\angle 2 = m\angle 6 = 60\°

Thus the measure of \angle 6\ is\ 60\°.

Find X- Y if X= 1/4 and Y= -X <br><br> A) 1/3<br> B) 1/2<br> C) -1/3<br> D)-1/2
77julia77 [94]

Answer:

Step-by-step explanation:

x = 1/4

y = -x = -1/4

x-y=\frac{1}{4}-(-\frac{1}{4})\\\\=\frac{1}{4}+\frac{1}{4}\\\\=\frac{1+1}{4}\\\\=\frac{2}{4}\\\\=\frac{1}{2}
