Answer:

x = 44

Step-by-step explanation:

Adjacent angles in a parallelogram add up to 180 degrees.

180 = 3x + 6 + 42

132 = 3x

x = 44

Answer:

Step-by-step explanation:

In each parallelogram angles at one side add up to 180°.

Therefore we have the equation:

$(3x+6)+42=180$

$3x+(6+42)=180$

$3x+48=180$ <em>subtract 48 from both sides</em>

$3x=132$ <em>divide both sides by 3</em>

$x=44$

Which of the following sets of numbers could be the lengths of the sides of a triangle?

kicyunya [14]

Answer is C. 8, 3, 6

To answer this, you must know the Triangle Inequality Theorem.

The two shortest sides when added together, must be greater than the longest side.

A. 2 + 4= 6 which can't work since it equals the longest side of 6

B. 4 +2=6 The sum would be less than 8, which doesn't work

C. 6 +3 = 9 the sum is greater than 8, which makes it a triangle

D. 3 +8 = 11 11 is less than 12

The given line passes through the points (-2,-4) and (2,2) What is the equation, in point-slope form, of the line that is parall

Morgarella [4.7K]

Answer:

$(y-1)=\frac{3}{2}(x+3)$

Step-by-step explanation:

The point slope form of a line is $(y-y_1)=m(x-x_1)$ where $x_1=-3\\y_1=1$ . We write

$(y-1)=m(x--3)\\(y-1)=m(x+3)$

Since the line is parallel to the line shown it will have the same slope. To find m, count the slope from each marked point on the graph. Count the rise then the run and create a fraction rise/run. The slope is 6/4 which simplifies to 3/2. Now substitute it for m.

$(y-1)=\frac{3}{2}(x+3)$
