Answer:
--- of perimeters
--- of areas
Step-by-step explanation:
Given
Represent the sides of the first triangle with x, y and z
The sides of the second triangle will be 6x, 6y and 6z
Solving (a): Ratio of perimeter.
The perimeter of the first is:
The perimeter of the second is:
Factorize:
The ratio is:
Cancel out x + y + z
Solving (a): Ratio of Areas.
If the height of the first is h and the base is b.
The height of the second will be 6h and the base, 6b.
The area of the first is:
The area of the second is:
The ratio is:
Divide by 0.5bh
The picture in the attached figure
we know that
If line GJ bisects the angle FGH, that means we also know that the angle FGH is divided into two equal sizes.
Now, we have
Angle FGJ = Angle HGJ
Angle GJF = Angle GJH
This information means that angle GHJ = angle GFJ
We have two congruent right-angled triangle
We can then further deduce that
Side GF = Side GH
Since triangle FGJ and triangle GJH are congruent,
then
side FJ equals to side JH
3x-8=16
3x=16+8
3x=24
x=8 units
Hence,
the length of FH = 2×8=16 units
the answer is
FH=16 units
