What is the equation of the line perpendicular to y= 2/3x+1 that passes through the point (12, 6)?

charle [14.2K]

Answer:

y=(-3/2)x+24

Step-by-step explanation:

a perpendicular line should have the negative reciprocal of the line that it is perpendicular to.

negative reciprocal of 2/3 is -3/2

out line should look something like this

y=(-3/2)x+b

then we use the given point to find b

6=(-3/2)12+b

6=-18+b

b=24

All the angles inside a triangle add up to 180°.

(2x + 15) + (5x + 5) + x = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/8
x = 20
the question is asking what angle B is,
B = 2(20) + 15
B = 40 + 15
B = 55°
