Step-by-step explanation:
Dilation refers to a non rigid motion where a figure is transform and its image has the same form but a different size measure.
Dilation is define by the rule (x,y)-- (kx, ky) where k represents the scale factor.
On this exercise is given that a triangle with vertices (-2,1), (8,4), and (3,0) was dilated by a scale factor of four, and it is asked to find the vertices of the image of the triangle after the dilation occurred.
Pre-image Image
(-2,1) -- (-2*4,1*4) -- (-8,4)
(8,4) -- (8*4,4*4) -- (32,16)
(3,0) -- (3*4,0*4) -- (12,0)
The coordinates representing the vertices of the triangle's image are (-8,4), (32,16), and (12,0); meaning that the ordered pair which is not a coordinate for a point in the triangle's image is (2,1).
Answer:
D
Step-by-step explanation:
Height: h
Length: 2h + 15
Area = length × width
4h² + 42h + 90
2(2h² + 21h + 45)
2[2h² + 15h + 6h + 45]
2[h(2h + 15) + 3(2h + 15)]
2(h + 3)(2h + 15)
Width = 2(h+3) = 2h + 6
Length: 2h + 15
Difference:
(2h + 15) - (2h + 6)
2h + 15 - 2h - 6
9
Width is 9 feet shorter than the length
The supplementary angle of 120° is 60°.
So your answer is 60 degrees.
