Recall that the y-intercept is when the function passes the y-axis. This happens when x=0. Therefore, we can find our y-intercept by plugging x=0 into our function and solving for y.
6x + 9y = 18
6(0) + 9y = 18
0 + 9y = 18
9y = 18
y =2
Thus, our y-intercept is when x = 0 and y = 2, or (0,2).
x will be 67 because in each case the angles are alternate interior angle so we can prove x=67degree

Make ABC the subject
Substitute:
Answer:
60 sides
Step-by-step explanation:
The formula for the sum of the interior angles of a polygon with n sides is 180(n -2). The problem also tells you that each angle is 174, so the sum of the interior angles would also be 174n.
Then, you get the equation
180(n - 2) = 174n
180n - 360 = 174n
6n = 360
n = 60 sides.
