Answer:

m∠CDE < m∠DEC < m∠ECD

m∠D < m∠E < m∠C

Step-by-step explanation:

According to the angle-side inequalities theorem: In a triangle, the angle opposite to a longer side is larger, and vise versa, the side opposite to a larger angle is longer.

So, the order from smallest to largest is:

m∠CDE < m∠DEC < m∠ECD

m∠D < m∠E < m∠C

$x\leq\frac{2}{5}$

Step-by-step explanation:

So starting from the beginning...

$3x+3\leq -2x+5$

Subtract the 3 from both side and it will look like...

$3x\leq-2x+2$

Then add 2x from both sides and it will look like...

$5x\leq 2$

Finally divide by 5 to both sides and it will look like...

$x\leq \frac{2}{5}$

PQ has endpoint p(0,0)and Q(8,4) find the coordinates of the mid point pq

Vera_Pavlovna [14]

The answer is (4,2).

Midpoint formula:
$(x \: y) = ( \frac{x2 - x1}{2}) (\frac{y2 - y1}{2} )$
Find the x value:
$x = ( \frac{x2 - x1}{2} )$
Plug in the givens:
$x = \frac{8 - 0}{2} = \frac{8}{2} = 4$
Find the y value:
$y = ( \frac{y2 - y1}{2} )$
Plug in the values:
$y = ( \frac{4 - 0}{2} ) = \frac{4}{2} = 2$
