Answer:
80 degrees
Step-by-step explanation:
Inside the angles will add up to 180 degrees.
Therefore we need to add 130+105+45 = 280
Next, take 360-280= 80 degrees
- If you would like to check, look at the angle within the shape. Since it is a little less than a right angle (90 degrees) we know that 80 degrees is the correct answer.
