<h3>Answer: Third choice. \overline{AC} \perp \overline{BD}</h3>

==================================================

Explanation:

SAS stands for Side Angle Side. Note how the angle is between the two sides. To prove the triangles congruent with SAS, we need to know two sides and an angle between them.

We already see that BC = CD as shown by the tickmarks. Another pair of sides is AC = AC through the reflexive theorem.

The missing info is the angle measures of ACB and ACD. If we knew those angles were the same, then we could use SAS to prove triangle ACB is congruent to triangle ACD.

It turns out that the angles are congruent only when they are 90 degrees each, leading to AC being perpendicular to BD. We write this as \overline{AC} \perp \overline {BD}. The upside down T symbol meaning "perpendicular" or "the two segments form a right angle".

Someone pls help me I'm really struggling and the assignment is almost due
Grace [21]

Answer:

x<3 and x≥5

Step-by-step explanation:

Look at the circles and what is shaded on the number line.  The first circle is at x=3, and it's an open circle.  An open circle means that the interval does not include that point.  The arrow is going to the left, meaning x < 3.

The next circle is at x=5.  It is a closed circle, so the interval does include that point (so draw a bar under the less than/greater than sign).  Next, notice how the arrow is pointing to the right.  That means that the blue area is at x=5 and greater than x=5, so x≥5.

dimulka [17.4K]

Answer:

total cost= $5,814

Step-by-step explanation:

Total linear feet measured: (110 x 2) + (270 x 2) = 760 linear ft

total sq ft= 760 x (7) = 5320 sq ft

total linear ft x labor= 760 x 1.70 = 1292 labor

Total sq ft x Cyclone fencing cost= 5320 x .85 = 4522

the total cost is 1292 + 4522 = $5,814
