Answer:
x=30
Step-by-step explanation:
Find the value of x that will make A and B parallel
For A & B to be parallel, the interior angles must be supplementary, i.e.
4x+2x = 180
6x=180
x=30
When x=30, the interior angles are 120 and 60 which are supplementary.
Answer:
10
Step-by-step explanation:
the radius is half of the diameter
y = - 8x - 18
the equation of a line in ' slope-intercept form ' is
y = mx + c (m is slope and c the y-intercept )
here m = - 8 ⇒ y = - 8x + c
to find c substitute ( - 3 , 6 ) into the equation
6 = 24 + c ⇒ c = 6 - 24 = - 18
y = - 8x - 18 is the equation
