Complementary angles are two angles that add up to 90 degrees. To find the missing angle, subtract the given angle from 90°.
Let’s go through each one:
a. Given: 37° → 90 - 37 = 53°
b. Given: 23° → 90 - 23 = 67°
c. Given: 52° → 90 - 52 = 38°
d. Given: 46° → 90 - 46 = 44°
e. Given: 70° → 90 - 70 = 20°
f. Given: 56° → 90 - 56 = 34°
g. Given: 19° → 90 - 19 = 71°
h. Given: 60° → 90 - 60 = 30°
i. Given: 43° → 90 - 43 = 47°
j. Given: 18° → 90 - 18 = 72°
k. Given: 31° → 90 - 31 = 59°
l. Given: 68° → 90 - 68 = 22°
All calculations checked — each pair adds to 90°.
Final Answer:
a. 53°
b. 67°
c. 38°
d. 44°
e. 20°
f. 34°
g. 71°
h. 30°
i. 47°
j. 72°
k. 59°
l. 22°
