Given that triangle ABC is a right triangle, select a set of possible side length measures.

ad-work [718]

You didn't supply any rules or constraints so.... 1 in., 1 in., and 1 in.

You can use the Pythagorean Theorem to check if the side lengths are appropriate.

$a^2 + b^2 = c^2$

$1^2 + 1^2 = 1^2$ –this is true.

Triangles PQR and XYZ are similar.

laiz [17]

Answer:

Option A. 5.25 units

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

$\frac{PR}{XZ}=\frac{QR}{YZ}$

substitute the given values

$\frac{7}{XZ}=\frac{4}{3}$

solve for XZ

$XZ=7(3)/4\\XZ=5.25\ units$

E=6c^2-2c-1<br> F=-4c^2+7c+5<br> E+F=

kifflom [539]

Answer:

E + F = 2c^2 + 5c + 4

Step-by-step explanation:

E=6c^2-2c-1

F=-4c^2+7c+5

E+F= 6c^2 -2c -1 + -4c^2 + 7c + 5

E + F = 6c^2 - 4c^2 - 2c + 7c - 1 + 5

E + F = 2c^2 + 5c + 4

How does a scale factor change the size of a figure?

IceJOKER [234]

The scale factor can change how big or small a figure is, though it will still be similar. For example, a triangle with two sides measuring 3 & 3 (isosceles) are scaled in a factor of 6 (becoming larger).

3 x 6 = 18

The new triangle will have the sides measuring 18. Even though the triangles are not congruent, they are similar.

hope this helps
