C is the answer I believe
It should be different to 12
Line AD is congruent to line AB
Since angle ACB is congruent to angle ACD and the length of lines CB and CD are congruent, then the length of AD and AB have to be the same
Pepe is putting a fence in his backyard to enclose the garden in the form of a triangle.
In the garden already has sides enclosed with 8 feet and 5 feet.
We know a triangle is possible when sum of length of two sides > third side
so third side < 8 + 5
or third side should be less than 13.
The side needs a fence that is longer than 3 ft. and shorter than 13 ft.
We are given backyard to enclose a garden in form of a triangle.
First side 'x' = 8 feet.
Second side 'y' = 5 feet
Third side = z
Property of triangle : the third side must be smaller than the sum of the other two sides but greater than their difference
So, third side must be shorter than 13 feet
So, third side must be longer than 3 feet
Hence option B is correct :The side needs a fence that is longer than 3 ft. and shorter than 13 ft.
We can say about the length of line segment Y'Z' will increase by the length of 3
We can say that the length of line segment Y'Z' will increase by a scale factor of 2.
If a scale factor is 3, then the length of Y'Z' will be 7·3=21 units.
P.S. In the added picture you can see trapezoid ABCD that was dilated by a scale factor 3 about the origin. This may help to understand that all linear values after dilation become multiplied by scale factor.
a. 12.5 kg
f = ma
m = f/a = (2500 n)/(200 m/s²) = 12.5 kg
1 n = 1 kg·m/s²
