Answer:
x = 99°
Step-by-step explanation:
first: find the supplement to 123°:
180 - 123 = 57°
second: since all triangle interior angles total a80°:
180 - 42 - 57 = 81°
third: x = the supplement to 81°, so, x = 180 - 81 = 99°
The answer to this is set Z

Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes equals - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Consider the given equations
3x - 4y = 12 ( subtract 3x from both sides )
- 4y = - 3x + 12 ( divide terms by - 4 )
y =
x - 3 ← in slope- intercept form
with slope m = 
3y = 12 - 4x = - 4x + 12 ( divide terms by 3 )
y = -
x + 4 ← in slope- intercept form
with slope m = - 
Then
× -
= - 1
Since the product of their slopes = - 1 then the lines are perpendicular

Step-by-step explanation:
I think option 4 is the correct answer
Answer:
416 passengers
Step-by-step explanation:
Dont stress out, it’s just simple subtraction,
so A380 can transport 555 which is 139 more then 747
so subtract 555-139 which will give you 416 passengers.
