Answer:
Quadrant IV
Step-by-step explanation:
45.0×5.0=50.0 is the awser
Answer:
<em>-90 degrees</em>
Step-by-step explanation:
Draw a segment from the origin, point O, to point R. Draw a segment from the origin, point O, to point R'. The angle of rotation is the angle between segments OR and OR'.
The slope of segment OR is 2/3.
The slope of segment OR' is -3/2.
The slopes are negative reciprocals, so the segments are perpendicular.
The angle between the segments is 90 degrees. The rotation is counterclockwise, so it is a negative number of degrees.
The angle of rotation is -90 degrees.
Answer
(4x-5) = -20 (2x+8) = 2
Step-by-step explanation:
2 x − 8 = 2 2x-8=2 2x−8=2. Add 8 to both sides. Simplify 2 + 8 2+8 2+8 to 10. Divide both sides by 2. If its wrong then I’m very sorry but I’m sure this is correct.
So the formula for the area of a trapezium is
area = (a + b)/2 * h
*a is the short side
* b is the long side
*h is the height
so let's plug in the values we already know: area, long base, short base. Here's how the formula looks now...
6550 = (150 + 85)/2 * h
*so, we need to find 'h'
use algebra to find it.
6550 = (235/2) * h
6550 = 117.5 * h
6550/117.5 = h
h = 55.74 (approx)
