Answer:
A
Step-by-step explanation:
The segment BC joining the midpoints of 2 sides of the triangle is
Half the length of the third side, that is
x + 31 = 2(x + 19)
x + 31 = 2x + 38 ( subtract x from both sides )
31 = x + 38 ( subtract 38 from both sides )
- 7 = x → A
The answer would be A. There is a phase shift to the left. Because you are adding pi/6.
If the answer is an equation then it is:
x=(4y+15)/(5-3y)
