When you add the degrees of all the angles in a triangle you should get 180
A= 5x+5
B= 90
C= 3x+5
5x + 3x = 8x
5 + 90 + 5 = 100
8x + 100 = 180 this is the equation
-100 -100
————————
8x = 80 ➡️ divide BOTH sides by 8
x = 10
Now plug 10 into angles A and C
5(10)+5= 55
3(10)+5= 35
A= 55 , B= 90 , C=35
Answer:
GCF: 2r
Step-by-step explanation:
The Greatest Common Factor(GCF) is the biggest factor you can divide both numbers by. For these numbers we cannot divide by a bigger number than 2r, and that happens to be the greatest common factor because 4r can be divided by 2r.

Answer:
That's it nothing else?
Step-by-step explanation:
**Note / Protip**
Always substitute "a number" for your variable when reading worded equations!
With that being said...
<span>D. x - 6 = 15
Is your answer, since you are going to want to reverse it because of how the problem's worded, not c. because; c.'s worded equation would be
"A number less than six."
