Answer:

The whole thing is 180 so if you subtract 180 from 120 you get 60.

Answer:

60 degrees since a straight line is 180 degrees

Step-by-step explanation:

Since part of it is 120 degrees the other part must be 60 because 120 + 60 = 180

Answers

Answer:

[tex]y = 7x [/tex]

Step-by-step explanation:

To find the slope, which is

[tex] \frac{rise}{run} [/tex]

find how high up the y value goes before it intersects the x line at a specific point. It seems that they intersect at (70,10) which would be 70/10 or 7/1. 7/1 is just 7 so the slope of it is just that, 7. As for finding B, look at where the line starts, of it's above or below 0, then you would add or subtract whatever number it starts at (subtract for negative, add for positive). In this case it seems that the intercept is right at 0 so you would neither add or subtract anything. :)

Find the coordinate point for D that would make ABDC a rhombus.
Point A (2,2)
Point B (3,4)
Point C (4,1)
Point D (?)

A. (5,4)
B. (5,2)
C. (5,3)
D. (3,0)

Answers

Answer:

(5,3)

Step-by-step explanation:

I took the test and go it right!

The coordinate point for D is (5, 3). Therefore, option C is the correct answer.

What is a rhombus?

A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square. Look at the image below to understand the relationship of rhombus shape with parallelogram and square.

Given that, Point A (2,2), Point B (3,4) and Point C (4,1)

The coordinate point for D that would make ABDC a rhombus.

So, the coordinate point for D is (5, 3).

Therefore, option C is the correct answer.
