The answer is 60 degrees because the red thingy indicated that it is a 90 degree angle then you subtract that from 150 to get your answer= 60
Answer:
2/3/+3=3
Step-by-step explanation:
3x + 12 = 18 . . . . . (1)
-(3x + 12) = 18 . . . (2)
From (1): 3x = 18 - 12 = 6
x = 6/3 = 2
From (2): -3x = 18 + 12 = 30
x = 30/-3 = -10
Therefore, there are two solutions.
