Two lines to be parallel their slopes have to be equal.
so m1 = m = 4
y = mx + b ( Slope intercept form)
y = 4x + b
(3,0) is on the line:
0 = 12 + b
b = -12
y = 4x - 12
Step-by-step explanation:
x+50 = 180 because asim circle
x =180-130
x=150
Answer:

Step-by-step explanation:
Given


Required
Calculate the diameter
The area of a sector is:

Substitute values for Area and 

Divide both sides by 

Make
the subject



Take positive square roots of both sides



The diameter is then calculated as:
