300 degrees
5/3 x 180
Cancel the common factor of 3
5 x 60
Multiply 5 by 60 = 300
Convert to a decimal
300 degrees
4/10 because 10-6 is 4 :)
Answer:
10) Supplementary; 11) Supplementary; 12) Complementary
Step-by-step explanation:
Sum of supplementary angles equals 180° while sum of complementary angles equals 90°.
For question 10
x + 70° = 180° (sum of straight lines)
x = 180° - 70° = 110°
Hence, 70° and 110° are supplementary angles.
For question 11,
x + 85° = 180° (sum of straight lines)
x = 180° - 85° = 95°
Hence, 85° and 95° are supplementary angles.
For question 12,
x + 32° = 90° (sum of right angles)
x = 90° - 32° = 58°
Hence, 32° and 58° are complementary angles.
