Answer:
x = 48
Step-by-step explanation:
Supplementary angles sum to 180°
add the 2 angles and equate to 180
x + 3x - 12 = 180 ( add 12 to both sides )
4x = 192 ( divide both sides by 4 )
x = 48
Answer:
Step-by-step explanation:
the general equation of a line is y=mx+c
because the slop is 1/5, the equation of this line would be
with the coordinates (20,5) , take 20=x and 5=y
and substitute these values into the equation above.
you should get:
5= 4 + c
so c = 1
therefore, the equation of the line is:
