Answer:
180 degrees.
Step-by-step explanation:
Because the angle at the circumference is 90 degrees the arc joining the 2 other points = 180 degrees.
So x = 360 - 180 = 180 degrees.
Answer:
12°
Step-by-step explanation:
a right triangle implies there is an angle that is 90°
another angle is 78°
the third angle is 180 - (90 + 78) = 180 - 168 = 12°
