Answer:
12
Step-by-step explanation:
I just did 9 ÷ .75 = 12
Answer:

Step-by-step explanation:
Since two sides of the triangle are equal in length, we can conclude that
is an isosceles triangle. With this information, we can draw an isosceles triangle to find
. Since the base angles of an isosceles triangle are equal, we can solve for
:
(Angle sum of triangle is
)
(Base angles of isosceles triangles are equal, there is an image attached to show that
is one of the base angles)

The scale factor of dilation is
.
<h3>What is scale factor?</h3>
When describing an enlargement you must state by how much the shape has been enlarged or reduced.
Area of triangle B =
= 0.5 x 2 x 3
= 3 units
Area of triangle A =
= 0.5 x 4 x 6
= 12 units
Scale factor =
=
= 
Hence, the scale factor of dilation is
.
