In triangle FGH, GJ is an angle bisector of ∠G and perpendicular to FH.

Citrus2011 [14]

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

Hello!

The mean is the average. The median is the middle number of the data set, in terms of quantity. The mode is the number that appears the most. The range is the difference between the largest and smallest numbers in the set.

Therefore, our answers are below.

Range: Difference between largest and smallest data piece.

Median: Middle value of a set of data

Mode: most commonly occurring number(s)

Mean: the sum of the data divided by the quantity of the data items.

I hope this helps!

Simplify the expression. 7 √x • 7 √x • 7 √x

blsea [12.9K]

Answer:

√7x−49√x

Explanation:

First of all, expand by multiplying √7x⋅√x and √7x⋅7√7respectively:

√7x(√x−7√7)=√7x⋅√x−√7x⋅7√7

... you can express √7x as √7⋅√x...

=√7⋅√x⋅√x−√7⋅√x⋅7⋅√7

=√7⋅(√x)2−(√7)2⋅√x⋅7

... the operations squaring and taking the square root "eliminate each other"...

=√7⋅x−7⋅√x⋅7

=√7x−49√x

Hope that this helped!
