The expression 6x+13 can be used to find the perimeter. We add up all the expressions given in the image and then combine like terms.
Answer:
Smallest angle: 41°
Second angle: 57°
Third angle: 82°
Step-by-step explanation:
Let's call the smallest angle as 
<u>"while a third angle is twice the smallest"</u>: third angle is 
<u>"One angle of a triangle measures 16∘ more than the smallest":</u> 2nd angle is 
We know sum of 3 angles in a triangle is 180 degrees, so we can set up the equation and solve for x:

So smallest angle is 41°
The 2nd angle is 16+41=57°
third angle is 2*41=82°
Answer:
y^2-y^1/x^2-x^1
Step-by-step explanation:
Answer:

Step-by-step explanation:
x = 180 - 80 - 55 (Interior angles of a triangle add up to 180 degrees so if we need to find any unknown angle, we'll subtract all the other angles from 180)
x = 45 degrees
