2*2-1/3 yards= 4-2/ yards =14 feet.

Lines r and s are parallel.
slamgirl [31]

Answer:

B

Step-by-step explanation:

Since r and s are parallel lines, then

The angle adjacent to 1 is corresponding to 158 and are congruent, thus

adjacent angle to 1 = 158°

1 and 158° are adjacent and supplementary, so

∠ 1 + 158° = 180° ( subtract 158° from both sides )

∠ 1 = 22° → B

Hey Guys...I need help again... Which graph represents a proportional relationship?
sukhopar [10]

Answer:

A

Step-by-step explanation:

For a graph to be representative of a proportional relationship, it must meet the following criteria:

1) It is a straight line.

2) It passes through the origin point (0,0).

3) It is neither horizontal nor vertical*.

We can see that D is not a line. So, D is not a proportional relationship.

We can also see that B and C are vertical and horizontal, respectively. They also do not cross the origin.

The only choice that is a straight line and also crosses through the origin point is A.

So, our answer is A.

And we're done!

*Note: Vertical lines are not proportional because they are not a function.

Horizontal lines are not proportional because they has a constant of proportionality of 0, which can't be the case.

The interior angles of a parallelogram will always equal 360. The interior angles of a triangle are 180 if it is a equilateral triangle then the angles are 60 degrees each. You know 2 sides of parallelogram. The 100 degree and 90 degree. You can find the one opposing the x because it’s on a straight line and a straight line is 180 degrees if a triangle is 60 degree angle then the opposing angle to complete the straight line must be 180-60 so you get 120. You now know 3 sides. 120, 90 and 100
They should add up to be 360 so you can set up an equation like so
120+90+100+x=360
And x = 50
