Answer:
Option D. ,
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal
so
substitute values and solve for OD
therefore
the coordinate of point D is
the scale factor is equal to
Answer: D
Step-by-step explanation:
Answer:
n ≥ -9
Step-by-step explanation:
Let n = the number
8 <em>less than</em> a number means "n – 8", but
8 <em>less</em> a number means "8 – n," so
8 – n ≤ 17 Subtract 8 from each side
-n ≤ 9 Multiply each side by -1
n ≥ -9
<em>Note</em>: When we multiply by a negative number, we must reverse the inequality.
<em>Check:</em>
Try n = -8.
8 – (-8) ≤ 17
8 + 8 ≤ 17
16 ≤ 17
<em>True</em>.
Answer:
The length of the rhombus is =
Step-by-step explanation:
It is given that the Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC.Then,
AE is the angle bisector of ∠A, so divides the sides of the triangle into a proportion:
⇒
⇒
Now, ΔDBE is similar to ΔABC, then
DE=
=
=
Thus, the length of the rhombus is =
