Answer:

The four angles are;

30 degrees,  85 degrees, 95 degrees , and 150 degrees

Step-by-step explanation:

Call the four angles of this quadrilateral A, B, C, and X (being X the smallest angle)

Then angle A is 55 degrees larger than X , therefore we can write it as X+55

Angle B is 65 degrees larger than X , therefore we can write it as X+65

Angle C is 120 degrees larger than X , therefore we can write it as X+120

Then we know that the addition of all four angles of a quadrilateral must give 360 degrees , so we have:

X + X + 55 +X + 65 + X + 120 = 360

that is:

4 X + 240 = 360

4 X = 360 -240

4 X = 120

X = 120/4

X = 30 degrees

and the other angles are:

30 + 55 = 85 degrees

30 + 65 = 95 degrees

30 + 120 = 150 degrees

What number is greater 0.111 or 1.001. also 1.11 or 1.01
Paul [167]
1.001 is greater than 0.111 because the 1 is automatically greater than zero.  1.11 is greater than 1.01 because there is a place in the tenths place in 1.11 but none for 1.01.

Can you make a graph that models the equation 4x + 2y = 8?
Ugo [173]
One of the easier ways to graph this line is the intercept method:

First, let x=0.  Then 2y=8, and y=4.  The y-intercept is (0,4).

Next, let y = 0.  Then 4x = 8.  The x-intercept is (8,0).

Plot these 2 points.  Then draw a straight line through them.

Solve for k. 9/2k-3=4/k+1
Ivenika [448]
You'll need to use parentheses here to convey this problem accurately to possible helpers.  Unsure of whether you mean (9/2)k -3 or  9 / (2k-3).

I will assume that you mean:

    9           4
------- = ---------
2k-3        k+1

Cross mult:  9k+9=8k-12, so k= -21.

If that's not what you expected, then try again to present the problem without ambiguities.
