Answer:
9. not possible
13, 14, 19. AAS — 13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF
15, 16. not possible
Step-by-step explanation:
9. You're looking for three sides, or two sides flanking a congruent angle. Here, the angle is not between the two sides, so the SAS theorem does not apply. Proving congruence is not possible.
__
13, 14, 19. You have two adjacent angles, followed by a side, so the AAS theorem will prove congruence.
When you write the congruence statement, you need to make sure the nodes are named in corresponding order. It can be useful to name the nodes in the same order as the elements you claim for congruence. For these, we name the two angle nodes first, then the other end of the side.
13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF
__
15, 16. With only one angle and one side, it is not possible to prove congruence.
_____
Additional comment
With these theorems, you are looking for angles or sides that are adjacent (next to each other). In figure 9, there are two sides and an angle, so you might be tempted to claim SAS congruence. The name SAS means the angle must be between the two sides. In that figure, the two sides are adjacent, and the angle is adjacent to only one of the sides (not between them). Hence SAS does not apply.
(You will find later that two sides and a non-adjacent angle will define a unique triangle if, and only if, the angle is opposite the longest of the two given sides. In figures like these, no side lengths are given, and you are not allowed to rely on appearances.)

Key skills needed: Proportions, Cross multiplication, One variable Equations, Multiplication
1) Since this is a proportion, we need to cross multiply. A proportion is just 2 fractions equal to each other in this format.
---> Cross multiplication is when you multiply the first fraction's numerator by the second fraction's denominator, and you multiply the first fraction's denominator by the second fraction's numerator.
---> You set these products equal to each other.
2) So if we cross multiply it would be: 3(3x+5) = 5(3-2x)
---> If you multiply everything out, it would be --> 9x + 15 = 15 - 10x
3) Move the x terms to one side and the numbers to the other side
---> 9x + 10x = 15-15
4) Combine like terms (9x+ 10x= 19x) (15-15=0) 19x = 0
5) Divide by 19 and x=0.

when the card is opened it illustrates a reflection over the fold of the card.
Which figure below could be used as the center of the invitation
Answers
Answer:
D
Step-by-step explanation:
The given sheet of paper is folded horizontally, thus a pattern with respect to the fold is formed inside the paper. This pattern would in the form of two lines crossing each other at right angles.
To illustrate a reflection over the fold of the card, the pattern in option D could be used as the center of the invitation.
Therefore, the correct option is D.

how do I find the area with only the height and diameter? HELP QUICK PLS!!
Answers
Answer:
The formula for the area of a circle is A = π r2, where r is the length of the radius of a circle. We can use our knowledge that a diameter is made up of two radii to understand that r = d/2. With this knowledge, you can rewrite the formula for the area of a circle as A = π (d/2)2.

Angle 1 and angle 2 form a linear pair. If the measure of angle 1 = (5x+9)º and
the measure of angle 2 = (3x+11)º, find the measure of each angle.
X =
angle 1 =
angle 2 =
Answers
- linear pairs are supplementary, meaning they add up to 180°
5x + 9 + 3x + 11 = 180
8x + 20 = 180
8x = 160
x = 20
- now plug in.
angle 1: 5(20) + 9 = 100 + 9 = 109°
angle 2: 3(20) + 11 = 60 + 11 = 71°

You and 3 friends decide to split a box
of one dozen donuts. Together, the
amount spent for the donuts is $17.45. If it costs $1.25 to park, how much did each donut cost per person?
WRITE AN EQUATION and solve.
Please hurry
Thx
Answers
Answer:
Step-by-step explanation:
Number of individuals = 4
Cost of dozen donuts with transport = $17.45 + $1.25
= $18.7
Since there are 12 pieces in a dozen pack of donuts, then the amount of each donut is:
= $18.7/ 12
= $1.56
So, if four people share a dozen donut, each person will have:
= 12/4
= 3 donuts each
and the price each person will pay for the three donuts will be:
= $1.56 × 3
= $4.68

Step-by-step explanation: To solve for X, we'll need to move all terms that don't contain X to the right and solve.
1. Add 16 to both sides
30x - 16 + 16 = 14 + 16
30x = 30
2. Divide both sides by 30
