Answer:

y=-1/3x-1

Step-by-step explanation:

Perpendicular lines have slope that are opposite sign and reciprocals

3x-y=12 has a slope of 3, therefore perpendicular line must have slope of -1/3

2=-9(-1/3)+b

2=3+b

b=-1

In circle J with \text{m} \angle HLK= 30^{\circ}m∠HLK=30

Answer:

The minor arc HK is 60 degrees

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The inscribed angle is half that of the arc it comprises.

$m\angle HLK=\frac{1}{2}(arc\ HK)$

we have

$m\angle HLK=30^o$

substitute the given value

$30^o=\frac{1}{2}(arc\ HK)$

$arc\ HK=60^o$

Remember that the measure of the minor arc must be less than 180 degrees

therefore

The minor arc HK is 60 degrees

How do you find the value of x for this figure?

Studentka2010 [4]

The 2 lines intersect, and by definition it will create equal opposite angles. Since we know that the angle created is 125 degrees, then the angle on the opposite side also must equal 125 degrees. But wait, they broke up the angle into 2 angles made up of a 64 degree angle and an X degree angle. These 2 angles must add up to 125 degrees.

x + 64 = 125
x = 125 - 64
x = 61 degrees
