what is the value of x? enter your answer in the box

Answer:
[tex]\boxed{x = 45\ degrees}[/tex]
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
Answer: 45
Step-by-step explanation:
The sum of a triangle's angles will always be 180 degrees. If we subtract 80 and 55 from 180, we will get the missing angle.
[tex]180-80-55=45[/tex]
Thus, the missing angle is 45 degrees.
