Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m
The area of the inscribed triangle = 3(6^2 x sin 120°) = 3(36sin 120°) = 3(31.18) = 93.53 square in.
That quadrilateral is a parallelogram. Parallelograms have 4 sides and the opposites side are parallel to each other.
Answer:
B ) The slope of the triangle P and Q is equal to 2
Step-by-step explanation:
slope of a line, in this case is hypotenuse, is given by rise by run.
For triangle P
Here rise is 6 units and run is 3 units
slope= rise/run = 6/3 = 2
Also for triangle Q
rise is 3 and run is 1.5
hence slope= 3/1.5=2
hence 2 is the answer
