M=y2-y1/x2-x1
m=12-4/-6--2
m=8/-4
m=-2
The formula for the area of a rectangle is A=l*w.
A=3/5 l=7/8
3/5=7/8w
multiply both sides by 8/7
x=24/35 or 33.6
Answer: RA, EJ, JT
Explanation:
When dealing with 3 dimensional figures, you must handle three concepts to analyze the spatial relationship of the lines. Those are:
- Perpendicular lines: it refers to lines that intersect each other at a 90° angle (right angle). This only can happen if the lines.
- Skew lines: it refers to lines that are not parallel but are in different planes and cannot not intersect each other.
- Parallel lines: are lines that are in the same plane but cannot intersect each other.
The given figure is a perfect model to understand what each one of those concepts mean.
Starting by the segment JA, you find that:
- The segments EH, QP, and TR are parallel to segment JA, because you can find a plane formed by JA and any of those segments, and yet JA will never intersect any of them.
- Segment JA is skewed respect segments QT, PR, QE, and PH, because they are in different planes.
- Segment JA is perpendicular to EJ, HA, JT and RA, because JAintersects any of them on a right angle.
Hence, the right choices are segments RA, EJ and JT
Answer:
the answer should be C.
Step-by-step explanation:
When two straight lines intersect each other at 90˚ or are perpendicular to each other at the intersection, they form the right angle. A right angle is represented by the symbol ∟.
