Two right triangles are graphed on a coordinate plane. One triangle has a vertical side of 3 and a horizontal side of 7. The other triangle has a vertical side of 9 and a horizontal side of 21. Could the hypotenuses of these two triangles lie along the same line? (4 points) Yes, because they are both right triangles Yes, because they are similar triangles No, because they are not similar triangles No, because one is larger than the other Description

Answers

Answer: Yes, because they are similar triangles

Step-by-step explanation:

Let ABC be the right triangle with vertical side of 3 and a horizontal side of 7.

And, right angle at B,

Then, AB = 3, BC = 7 ⇒ AC = √58

Again let, DEF be the right triangle with vertical side of 9 and a horizontal side of 21.

And, right angle at E,

Then, DE = 9, EF = 21 ⇒ DF = 3√58

Thus, in triangles ABC and DEF,

Therefore,

By the property of similar triangles,

Since, in both triangles horizontal sides BC and EF are on X-axis,

Therefore,

The second one is correct

Answer:

Yes

explanation: they are similar triangles

Answer:

5 or -2

Step-by-step explanation:

simplify this to make it easier.

$x^(2) +2x-2x-4=3x+6\n$

then combine like terms

$x^(2) -4=3x+6$

now move everything over to the right

$x^(2) -3x-10=0$

then if you factor it, you get

$(x-5)(x+2)$
