As you can see in the picture, this is 6-8-10 right triangle.
One of angles is 90° so you can find others
8/6 = 4/3
6/8= 3/4
tan-1(4/3) = 36.9 °
tan-1(3/4) = 53.1 °
tan<R= 53.1 °
Hope this helps ^-^
Answer:
the answer would be 4 because you multiply
Answer:
42 candles
Step-by-step explanation:
Firstly, we need to find the surface area of the pyramid used. This can be obtained by finding the area of the base, multiplied by the height of the pyramid.
The area of the base since it is rectangle is L * B and that is 5 * 2 = 10cm.sqr
The volume of the pyramid is A * h and that is 10 * 12 = 120cm.cub
To fInd the number of candles used , we simply divide the volume of wax by the volume of a candle.
That is 5040/120 = 42 candles
Answer:
<em>Reflecting over the x-axis and then reflecting over the line y = x. </em>
Step-by-step explanation:
<em>A rotation 90° counterclockwise will map every point (x, y) to (-y, x).</em>
<em></em>
<em>Since the x- and y-coordinates are switched, this is not a reflection across the x-axis followed by a reflection across the y-axis.</em>
<em></em>
<em>Since the y-coordinate is negated and the x- and y-coordinates are switched, this is not a translation.</em>
<em></em>
<em>Reflecting across the x-axis will negate the y-coordinate, giving us (x, -y). Following this with a reflection across y=x will switch the coordinates giving us (-y, x). This is the correct transformation.</em>
Notice the picture above, the "diameter" is 4.3, meaning its radius is half that, or 2.15, and it has a height of 4.7.
