Answer:
P(-2,7)
P'(-2,-7), ANSWER
reflection across the x-axis rule:
(×,y) ===> (x,-y)
Easy way to do this is draw the point on graph paper and count the same units above/below the x-axis. This example you are 7 units above the x-axis so you would count 7 units below the x-axis giving you the point.
Answer:
73.72
Step-by-step explanation:
Using law of Sines in area:
A(triangle) = S1 * S2 * sin(theta) /2
A(triangle) = 12 * 15 * sin(55) / 2 = about 73.72 when rounded

Answer:
<h2>The answer is 9.4 units </h2>
Step-by-step explanation:
The distance between two points can be found by using the formula
<h3>
![d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} }](https://tex.z-dn.net/?f=d%20%3D%20%20%5Csqrt%7B%28%20%7Bx1%20-%20x2%7D%29%5E%7B2%7D%20%2B%20%20%28%7By1%20-%20y2%7D%29%5E%7B2%7D%20%20%7D%20)
</h3>
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(0,5) and (8,0)
So the distance between them is
<h3>
![d = \sqrt{ ({0 - 8})^{2} + ({5 - 0})^{2} } \\ d = \sqrt{ ({ - 8})^{2} + {5}^{2} } \\ d = \sqrt{64 + 25} \\ \\ d = \sqrt{89}](https://tex.z-dn.net/?f=d%20%3D%20%20%5Csqrt%7B%20%28%7B0%20-%208%7D%29%5E%7B2%7D%20%2B%20%20%28%7B5%20-%200%7D%29%5E%7B2%7D%20%20%7D%20%20%5C%5C%20d%20%3D%20%20%5Csqrt%7B%20%28%7B%20-%208%7D%29%5E%7B2%7D%20%2B%20%20%7B5%7D%5E%7B2%7D%20%20%7D%20%20%5C%5C%20d%20%3D%20%20%5Csqrt%7B64%20%2B%2025%7D%20%20%20%5C%5C%20%20%5C%5C%20d%20%3D%20%20%5Csqrt%7B89%7D%20)
</h3>
d = 9.4339811
We have the final answer as
<h3>d = 9.4 units</h3>
