Question

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

Answer 1

Answer:

$\boxed{x = 45\ degrees}$

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 2

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.

$180-80-55=45$

Thus, the missing angle is 45 degrees.
