Answer:
x = 20
ABC = 85
BCA = 81
CAB = 14
Step-by-step explanation:
I answered your other question, so basically just read the explanation there cuz I'm too lazy to write it again :P
Answer:
use a ruler
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
Extend line AB so that it intersects ray CE at point G. Then angles BGC and BAD are "alternate interior angles", hence congruent.
The angle at B is exterior to triangle BCG, and is equal to the sum of the interior angles at C and G:
138 = (376 -23x) +(x^2 -8x)
Subtracting 138 and collecting terms we have ...
x^2 -31x +238 = 0
For your calculator, a=1, b=-31, c=238.

<em>Additional comment</em>
You will find that the solutions to this are x = {14, 17}. You will also find that angle BCE will have corresponding values of 54° and -15°. That is, the solution x=17 is "extraneous." It is a solution to the equation, but not to the problem.
For x=14, the marked angles are A = 84°, C = 54°.
Answer:
The variable y is eliminated.
Step-by-step explanation:
To add a system of equations, we add the common terms. x with x, y with y and values with values.
In this question:
5x + 6y = 32
5x – 6y = 8
Adding:
5x + 5x + 6y - 6y = 32 + 8
10x = 40
So the variable y is eliminated.
Given:
Whiskers the cat weighs 
kg and Pilglio weighs 5 kg.
To find:
How many times as heavy as pilglio is whiskers?
How many times as heavy as whiskers is pilglio?
Solution:
We have,
Weight of cat (whiskers) = kg
= 
kg
= 
kg
= 3.5 kg
Weight of pilglio = 5 kg
Now,
Therefore, whiskers is 0.7 times as heavy as pilglio.
Therefore, piglio is about 1.43 times as heavy as whiskers.
