Draw scalene triangle ABC and extend side BC to the right of vertex C. 1. If angle A measures 45 degrees and angle B measures 60 degrees, what is the measure of the exterior angle you drew?

2. Explain how you found the answer.

3. What do you observe?

Mark Brainliest please

See the image for the drawing
Let’s say the side BC is extended till D

1) measure of angle ACD = 105° ( angle ACD is exterior angle)
45 + 60 = 105
2) I found the answer by adding the values of Angle A and Angle B or by using the exterior angle property.
3) I observed that exterior angle property can be used here. Exterior angle property is that an exterior angle of a triangle is equal to the sum of the opposite interior angles.
