Answer:
From the given triangle figure;
Labelled the triangle as A , B and C.
The coordinates of this triangle ABC are;
A = (1, 10) ,
B = (-2, 4)
C = (7, 4).
Given : Scale factor(k) =
and centered at point (4, -2).
The rule of dilation with
and center at point (4,-2) is:


or

then, the dilation of the given figure are;
=
=
= A'(3 , 2)
=
=
=B'(2 , 0)
=
=
= C'(5 , 0)
The coordinates of dilation images are:
A' = (3,2) , B' = (2, 0) and C' = (5, 0)
You can see the graph of the dilated image as shown below:
Answer:
c. 441ft^2
Step-by-step explanation:
Area is height times length and since it's a square, safe to say that the sides are equal in length. So square root both of the given areas of the 2 square:
= 29
= 20
Now u have side b and c of the triangle, it's a right triangle so use the Pythagorean theorem a^2 + b^2 = c^2
a^2 + b^2 = c^2
a^2 + 20^2 = 29^2
a^2 + 400 = 841
subtract 4 from both sides
a^2 = 441
square root both sides

a = 21
Now the side a of the triangle is also a side of the small square therefore
21^2 = 441
Answer:
10.57 cm²
Step-by-step explanation:
Recall that the area of a triangle is gotten by (1/2)*base*height
If the height of the triangle is 5.45cm and the base is 3.88cm, then the area can be calculated by multiplying the two numbers and dividing it by 2.
5.45*3.88 = 21.146cm²
This still needs to be cut in half (otherwise we are yielding the area of a rectangle with these dimensions)
21.146 cm²/2 = 10.573 cm²
This can be rounded to the nearest hundredth
= 10.57 cm²
