angle.​

Answer 1

Answer:

Step-by-step explanation:

3. You did not write how much less

3. Complement of an angle = 90°

Half of the complement = 45°

30 more than half of the complement = 45+30 = 75°

3. Supplement of an angle = 180°

Let the measure of the angles be x

4x +5x = 180°

9x = 180°

x = 180/9

X = 20

4x= 4* 20= 80°

5x = 5*20 = 100°
