Answer:
100 degrees
Step-by-step explanation:
The angle x is opposite the angle that is 100 degrees.
Since they are opposite each other, they are vertical angles.
This means that they are congruent, or equal to each other.
Therefore,
x=100
x is 100 degrees
AD = BC ----> Parallel lines
AC = AC -----> Reflexive property
<A = <C -----> Congruent angles
<D = <B -----> Congruent angles
Answer:
x=13
Step-by-step explanation:
if you will substitute the value of f(x) with 5, you will get the following equation:
5=2x-21
2x=26/÷2
x=13
(I didn't know what you ment when you wrote x2, is it x square or 2X)
I really hope it was the second one, cause that's how I solved it.

Step-by-step explanation:
Given



Required
True about area II and III
The question is incomplete; so, I will answer using general knowledge.
If the total area is:

And there are 4 areas, then;

Rewrite as:

This gives:

Collect like terms


Rewrite as:

<em>So, the sum of areas III and IV must be 14x</em>
