Question

Supplement of 129° geomitry

Answer 1

Made using 129° geomitry:
- The point of intersection of the east-west and north-south lines is at A.
- The point of intersection of the east-west and north-south lines is B.
- The point of intersection of the north-south line and the vertical line is at C.
- The point of intersection of the north-south line and the horizontal line is at D.

Answer 2

The supplement of a 129-degree angle is 51 degrees, because supplementary angles add up to 180 degrees.

Step-by-step explanation:

The supplement of an angle is what you add to that angle to get a total of 180 degrees. So, to find the supplement of a 129° angle, you would subtract the given angle from 180°. Therefore, the supplementary angle of 129° is calculated as follows:

• 180° - 129° = 51°

The supplement of a 129° angle is a 51° angle.
