Answer:
x = 10
Step-by-step explanation:
Since the triangles are similar the ratios of corresponding sides are equal
=
, that is
=
( cross- multiply )
20(4x + 2) = 84x
80x + 40 = 84x ( subtract 80x from both sides )
40 = 4x ( divide both sides by 4 )
x = 10

Answer:
The line is
Step-by-step explanation:
From the question we are told that
The line is
The point is P(0,0 )
Generally the equation for a line is
Now comparing this with the given equation we see that
Generally the slope of the perpendicular to the given line is mathematically evaluated as
=>
=>
Generally from the univesal equation of a line and the given point we have that
y = mx + c at p(0,0) and is
0 = -4 (0 ) + c
=> c = 0
Hence the equation perpendicular to the line given at the point given is
