A straight line is 180°.

The sum of all the angles in a triangle is also 180°.

Let the missing angle be x°.

For the straight line:
x + 2x²+ 3x+ 6 = 180

x = 180 - (2x² + 3x + 6)

x = 180 - 2x² - 3x - 6

x = 174 - 2x² - 3x

For the missing angle in the triangle:
(174 - 2x² - 3x) + 8x + 3x² - 6x = 180

174 - 2x² - 3x + 8x + 3x² - 6x = 180

174 + x² - x = 180

x² - x + 174 - 180 = 0

x² - x - 6 = 0

(x + 2)(x - 3) = 0

x + 2 = 0 or x - 3 = 0
x = -2 or x = 3


The answer is x = -2 or x = 3

Can someone help me with this please

Ok so we'll  go ahead and solve for y first -  we just need to get it alone on one side of the equal sign

Step 1: subtract 2x from each side

2x - 7y - 2x = 19 - 2x

This cancels out the 2x on the left, giving us

-7y = 19 - 2x

Step 2: divide both sides by -7

\frac{-7y}{-7} = \frac{19}{-7} + \frac{-2x}{-7}

This gives us

y = -19/7 + 2x/7

That should be your answer for the first question. Now solving the next parts are easy. All you need to do is plug in x.

When x = -3

y = -19/7 + 2x/7

y = -19/7 + 2(-3)/7

y = -19/7 - 6/7

y = -25/7


When x = 0

y = -19/7 + 2x/7

y = -19/7 + 2(0)/7

y = -19/7


When x = 3

y = -19/7 + 2x/7

y = -19/7 + 2(3)/7

y = -19/7 + 6/7

y = -13/7


Hope that helps! Feel free to ask if I can help with anything else :)

How to find the area of a tilted square?
Katena32 [7]
A square has 4 sides of equal legnths
in your point of view, it looks tilted because it is actually a rhombus, a paralellogram (4 sided figure with 2 pairs of paralell sides) with 4 equal sides

to find the area, just multiply  base by height (look at ilustration/attachmtns)

Answer:

.2 <em>or </em>1/5

Step-by-step explanation:

First, calculate the total points by adding the two half's totals together.

7 + 18 = 25

Now, divide the number of points Mary scored by the total.

5 / 25 = 1/5
