Answer 1

Answer:

Complement of 54° is 36°

Solution for 3 (a + 5) = 24 is 3

Vertically opposite angles are equal

Sum of linear pair of angles is 180°

Supplement of 112° is 68°

Explanation:

(1) 1st angle = 54°

Complement = x

Sum = 90°

x + 54° = 90°

x = 90° - 54°

x = 36°

Hence, complement id 36°

(2) 3 (a + 5) = 24

3a + 15 = 24

3a = 24 - 15

3a = 9

a = 9 ÷ 3

x = 3

(3) Vertically opposite angles are equal.

(4) Pair of angles whose sum is 180° are called Linear Pairs

(5) 1st angle = 112°

Supplement = x

Sum = 180°

x + 112° = 180°

x = 180° - 112°

x = 68°

Hence, the supplement of 112° is 68°

Hope it helps

Answer 2

Step-by-step explanation:

complementary of 54°=(d) 36°

solution for. ....=(e) 3
