If you meant to write y=23x-4 then none of the lines are perpendicular.
I suspect you intended y=2/3x-4, then line D, y=-3/2x-4 is perpendicular.
For any line y=mx+b, you have to "invert" m to get a perpendicular line. Inverting in this case means: flip numerator and denominator and add a minus sign.
So 2/3 becomes -3/2, hence answer D.
The 'inverted' m is called the opposite reciprocal. That's your word of the day.
Answer:
the answer is the 4th one
Step-by-step explanation:
Let , missing value(_)=A
As, it is given that ,

To convert the value of A into Radians,
360°=2 π Radians

So, missing value to the nearest hundredth= 1.26 Radians

Step-by-step explanation:
No trapezoid is attached; so, I will solve on a general note
The area of a trapezoid is:

Using the attached image as a point of reference;
The parallel sides are: AD (6cm) and BD (12cm)
The height is 4cm
So, the area is:
