A parallelogram is a four sided plane rectilinear figure with opposite sides parallel. Rotation transformation can be verified with a parallelogram.
Answer:
Step-by-step explanation: what is the last word
Answer:
255 m
Step-by-step explanation:
From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.
Thus,
For the aircraft, its height = +200 m
For the submarine, its depth = -55 m
So that the difference between the submarine and aircraft can be determined as;
200 - (-55)
= 200 + 55
= 255 m
The distance between the submarine and aircraft is 255 m.
Answer:In a square or other rectangle, all pairs of adjacent sides are perpendicular. A right trapezoid is a trapezoid that has two pairs of adjacent sides that are perpendicular. Each of the four maltitudes of a quadrilateral is a perpendicular to a side through the midpoint of the opposite side.
A right triangle has 1 90 degree angle and the interior angles must add to 180.
3(x+8)+x+90=180
3x+24+x+90=180
4x+114=180
4x=66
x= 16.5
Plug this value in to find the last angle
16.5+90+x=180
106.5+x=180
x=73.5
Final answer: 73.5 degrees and 16.5 degrees
