<span>D) right
The slope between </span>(3,-2) (7,3) and <span>(3,-2) (-7,6) are opposite reciprocals of 5/4 and -4/5. If the slopes are opposite reciprocals they are perpendicular and have an angle equal to 90 degrees which makes it a right triangle. none of the distances are equal so it cannot be an isosceles right triangle.</span>
Answer: 9
Step-by-step explanation: subtract 60 from each side to get -72 = -8x = 9
Answer:
<h2>181.33</h2>
Step-by-step explanation:
Since the base of the pyramid PABCD is a rectangle, the shape in question is a rectangular based pyramid. Volume of a rectangular based pyramid is expressed as V = 1/3 * Base Area * Height of the pyramid.
Given a rectangle ABCD with AB = 8 and BC = 4, the area of the rectangle will be equivalent to the base area of the pyramid.
Base Area = Length * Breadth
Base Area = AB * BC
Base Area = 8*4 = 32
If , and PB = 17, then the height of the pyramid is PB = 17.
Volume of the pyramid = 1/3 * 32 * 17
Volume of the pyramid = 1/3 * 544
Volume of the rectangular based pyramid = 181.33
