Answer:
<u>SAS congruency:</u>
example---- figure attached.
<u>ASA congruency:</u>
What it says--- If any two angles and the included side are the same in both triangles, then the triangles are congruent.
Information required---- two pair of congruent triangles and one corresponding sides.
example----figure attached.
<u>AAS congruency:</u>
What it says----if two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.
Information Required----Two angles and a non-included side are congruent.
example---- figure attached.
<u>HL congruency:</u>
What it says---- When two right triangles have corresponding sides that are congruent , the triangles are congruent.
Information required---- two right triangles and the sides are congruent.
Example--- figure attached.

Answer:
4
Step-by-step explanation:
7x = x² - 8
=> x² - 7x - 8 = 0
use quadratic formula:
a = 1, b = -7, c = -8
x = <em>(pls ignore the "A" I don't know why it's showing up)</em>
=> x =
=> x =
=> x = = 4 or
= -5 <em>(the answer is only 4 since it's asking for the positive solution)</em>
Answer:
Final answer is c=-7.
Step-by-step explanation:
Given equation is .
Now question says that Misha wrote the quadratic equation 0=-x2+4x-7 in standard form. Now we need to find about what is the value of c in her equation.
We know that standard form of quadratic equation is given by .
compare given equation with the standard form, we find that -7 is written in place of +c
so that means +c=-7
or c=-7
Hence final answer is c=-7.
