To find the measure of each angle you add all of the sides
Then, all triangles equal 180
3x + 2x + x = 180
Like terms
6x = 180
/6. /6
X = 30
Now to find the measures of the angles
You plug in the value of x
1st angle =. 3x
3(30)
=90
2nd angle = 2x
2(30)
=60
3 angle =. X
=30
Glad I could help
Answer:
x+3
Step-by-step explanation:
If you factor 5 out of the denominator of the first expression, 5x+15 turns into 5(x+3).
Then, since you have x+3 in the numerator and denominator, it will cancel out.
The steps are shown below:

Ive attached an image that shows an example of simplifying an expression using a the same technique.
Answer:
the answer is: x>-8. I attached a picture explaining hope this helps
Answer: y=2
3y+2=6y-4
6=3y
y=2
