Determine the value of x in the triangle shown. answers : 180° 135° 90° 45°

Answer:
x = 135
Step-by-step explanation:
45 and x from a straight line so they sum to 180 degrees
45+x = 180
Subtract 45 from each side
45+x-45 = 180-45
x = 135
Answer:
x = 135°
Step-by-step explanation:
The two angles form a 180° (straight) line. They are supplementary angles.
180° - 45° = 135°
