In a right triangle, if AB is 8m and mA is 42 degrees,<span> the length of AB would be 8.9 if B is the right angle, or 12 if C is the right angle.</span>
Answer:
See the explanation below.
Step-by-step explanation:
Starting from
By putting we have:
Answer:
32 ft
Step-by-step explanation:
The perimeter is basically the area of the outside of a shape. To calculate this, you would add up all the sides together and get the answer.
8 + 8 + 8 + 8=32 or you can just do 8*4 which is also 32
So, the answer is 32
Answer: Quadrant 2
=================================================
Explanation:
Check out the diagram below. An example point in the third quadrant is (-2,-5). This quadrant is the southwest quadrant. Reflect the example point over the x axis (aka the line y = 0) and we get (-2,5). This is shown when we go from point A to point B in the diagram.
The reflection rule is showing that only the y coordinate changes from y to -y. If y is negative, then flip to positive, or vice versa. The x coordinate stays the same.
The point started in quadrant 3 and it moves to quadrant 2 after the reflection over the line y = 0.
Side note: all points on the line y = 0 have a y coordinate of 0
A rotation of 90 degrees changes (x,y) to (-y,x). If the original coordinates if point F is (0,3), after a rotation of 90 degrees it would be (-3,0).
