The measure of segment GH would be 10.4 also

For a better understanding of the explanation provided here please go through the diagram in the attachment given below.

As we can see from the diagram of the congruent triangles ABC and FGH, the vertices A,B,C of \Delta ABC correspond to the vertices F,G,H of \Delta FGH, so the corresponding sides must correspond too. Thus, AB corresponds to FG, BC corresponds to GH and CA corresponds to GF.

Now, we know that BC=10.4. Therefore, it's corresponding side GH must be 10.4 too because they are corresponding sides of a congruent triangle.

Thus, GH=10.4 is the correct answer.

By the law of cosines, the angle C satisfies

8.77^2=2^2+9^2-2\times2\times9\times\cos C

which reduces to

\cos C=0.2246\implies C=\arccos(0.2246)\approx1.34422\text{ rad}

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).

I only need help with number 9 plz
Varvara68 [4.7K]

Answer:

<h2>Letter C</h2>

Step-by-step explanation:

If we look on the number line we see that there is a point on -3, another point on -1, 2, and 7.

These points tell us our answer, but the question states it doesn't have to be in any order.

As we look at answer A we see -3, 1, 2, and -7. That's incorrect since there is no positive 1 nor an -7.

As we look at answer B we see -3, 7, 1, and -2. That's incorrect since there is no positive 1, and not a -2.

As we look at answer D we see -2, 3, 1, and 7. That's incorrect since there is no positive 2, no positive 3, and no negative 1.

C has to be the correct answer since it's the only answer left and has the 4 numbers that are on the number line.

Therefore, the correct answer is C.

Best of Luck to you.
