Answer:

x = 128 degrees

Step-by-step explanation:

First figure out the angle inside the triangle

1st step: add 55 and 73 together:

⇒ 55 + 73 = 128

2nd step: subtract the sum from 180:

⇒ 180 - 128 = 52

to find x, take 180 again and then subtract 52 from it:

⇒ 180 - 52 = 128

First lest’s find the measure of the missing angle in the triangle we have the sup of the angles in a triangle is equal to 180 so the missing angle will be 180- 73-55 = 52
Now let’s find x we have a 180 degrees angle so to find x we have to subtract 52 from 180.
The answer will be x = 128 degrees
