Answer: 50 Degress
Step-by-step explanation: As we can see in the photo, this is half of a circle which is equal to 180 degress, because a full circle is 360 degress.
We already have the first two angles completed, so to make things simple we will add them
65 + 65 = 130
Next since we know the total of all three angles is 180 degress we will subtract that by the angles we already are shown, which is a total 130 degress
180 - 130 = 50
So angle C is 50 degress
