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
Step-by-step explanation:
complementary of 54°=(d) 36°
solution for. ....=(e) 3
vertical opposite angle=equal
