Answer:
yes (6,7) is a solution.
Step-by-step explanation:
(6,7) is an ordered pair, see it like (x,y). so
x=6
y=7
substitute the variable with the values.
x+y=13
6+7=13
13=13
this is a true statement.
The student made an error in <u>step 3</u>. To correct this error, he should define <u>side AY</u> in terms of <u>angle X</u>. <u>Pythagorean theorem</u> relates sides x, y, z, and <u>angle X</u>
<h3>The law of cosine.</h3>
In Trigonometry, law of cosine (cos) is given by this mathematical expression:
cosθ = Opp/Hyp
<u>Where:</u>
- Opp is the opposite side of a right-angled triangle.
- Hyp is the hypotenuse of a right-angled triangle.
In this scenario, we can logically deduce that the student made an error in <u>step 3</u>. To correct this error, he should define <u>side AY</u> in terms of <u>angle X</u>.
After correcting this error, the student can use the <u>Pythagorean theorem</u> to relate sides x, y, z, and <u>angle X</u>.

Answer:
asa
Step-by-step explanation:
it says that angle 6 and angle 9 are congruent and side om is congruent to side em and then the angle 7 and 8 are congruent because they are vertical angles and vertical angles are equal to each other. so it gives you angle side angle which is why the correct answer is asa
