No error - A and B are completely right, and using the subtraction law D is right
<u>Congruency</u> property relates to two or more <em>triangles</em> with similar <em>dimensions</em>, and internal<u> angles</u>. So that the required <u>statements</u> to complete the proof are:
1. <em>definition</em> of a <u>straight</u> angle.
2. <u>subtraction</u> property of equality
3. <em>corresponding</em> sides of <u>similar</u> triangles are <u>proportional</u>
4.<u> transitive</u> property of <em>equality</em>.
The <u>intersection</u> of two or more lines forms a number of <em>angles</em> which depends on the <u>number</u> of lines involved. These <u>angles</u> formed may have <em>similar</em> or<em> different </em>properties.
When two or more <u>triangles</u> have <em>similar</em> lengths of <u>sides</u> and measure internal <u>angles</u>, it can be said that they are congruent. Thus they have some <u>common</u> properties.
Therefore, the appropriate <u>statements</u> to answer the given <em>question </em>are stated below:
- <em>Definition</em> of a <u>straight</u> angle.
- <u>Subtraction</u> property of equality.
- <em>Corresponding</em> sides of <u>similar</u> triangles are <u>proportional.</u>
- <u>Transitive</u> property of <em>equality</em>.

Answer:
A. x= 3, y= -2
Step-by-step explanation:
[2] 2x= 4y+14
[1] 3y+5x=9
Solve equation [2] for the variable x
[2] 2x = 4y + 14
[2] x = 2y + 7
// Plug this in for variable x in equation [1]
[1] 5•(2y+7) + 3y = 9
[1] 13y = -26
// Solve equation [1] for the variable y
[1] 13y = - 26
[1] y = - 2
// By now we know this much :
x = 2y+7
y = -2
// Use the y value to solve for x
x = 2(-2)+7 = 3
good luck, I hope this helps!!!
