Parallel slope = 2

This is because the original line has slope 2. Parallel lines have equal slopes.

--------------------------

Perpendicular slope = -1/2

The original slope 2 or 2/1 turns into -1/2 after flipping the fraction and the sign. Note the original slope and perpendicular slope multiply to -1. This is true for any pair of perpendicular lines where neither line is vertical.

What is X= to and what does Y= to?
Jet001 [13]

Step-by-step explanation:

Straight line = 180 °

5x + 78 = 180

5x = 180 - 78

5x = 102

x = 20.4

and y = 78 ° because y is an opposite angle of 78 °

Add using the number line. 7+(−10) Drag and drop the word SUM to the correct value on the number line.
Amiraneli [1.4K]

Steps of adding 7+(-10) using number line are as following:


1) Draw a number line by ranging from -10 to +10.

2) Point out 7 on the number line.

3) Because -10 is added to 7 on the number line,  please move 10 numbers left to 7 on the number line. We always go left in addition of a negative number on the number line.

4) The number we reach -3 on left side would be our final sum.

5) From the number we can clearly see that moving 10 number on left to 7, we get -3.

Note: We are moving left because of negative sign in front of 10.

In this circle, the area of sector COD is 50.24 square units. The radius of the circle is units , and units.
maks197457 [2]

Let angle be alpha

\\ \rm\Rrightarrow Area=50.24

\\ \rm\Rrightarrow \dfrac{\alpha}{360}\pi r^2=50.24

\\ \rm\Rrightarrow \alpha 3.14r^2=18086.4

\\ \rm\Rrightarrow \alpha r^2=5760

\\ \rm\Rrightarrow r^2=\dfrac{5760}{\alpha}

\\ \rm\Rrightarrow r=\sqrt{\dfrac{5760}{\alpha}}

If you have angle measure in degree put in place of Alpha and get the value elaw this is our final answer

Please help me solve my problem!!!
Nookie1986 [14]

Answer:

B. sometimes

Step-by-step explanation:

Consecutive angles of a parallelogram are same side interior angles of two parallel lines cut by a transversal, so they are always supplementary.

Supplementary angles are two angles whose measures add to 180 deg.

If two angles are supplementary and one angle measures 90, then the other angle also measures 90 deg, and the two angles are congruent. If one angle measures less than 90 deg, then the other measure more than 90 deg and are not congruent. Therefore, these angles may or may not be congruent.
