Step-by-step explanation:
Answer:
9
-3x-12
9+6x-7-9x-5
(Group liked terms)
9+6x-9x-7-5
( subtract the numbers ) -7-5= -12
9+6x-9x-12
( add similar elements ) 6x-9x=-3x
9-3x-12

Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
∠1 = 180° - (72 + 57)° = 180° - 129° = 51°
The right angle at the left vertex is composed of 72° and ∠2, thus
∠2 = 90° - 72° = 18°
57° and ∠3 form a straight angle and are supplementary, thus
∠3 = 180° - 57° = 123°
∠4 = 180° - (∠2 + ∠3 ) ← sum of angles in a triangle
∠4 = 180° - (18 + 123)° = 180° - 141° = 39°
