If KM is drawn on this quadrilateral, what will be its length ???
2 answers:
Answer:
B. 18
Step-by-step explanation:
We have been given an image of a quadrilateral and we are asked to find the length of segment KM.
We can see from our given quadrilateral that its two sides are parallel that is KL||JM.
We can also see that its two opposite sides are equal that is .
Since we know that an equilateral trapezoid has parallel bases and equal opposite sides or legs, therefore, our given quadrilateral is an equilateral trapezoid.
Since diagonals of equilateral trapezoid are congruent, therefore, the length of KM is 18 units and option B is the correct choice.

Step-by-step explanation:
circumference = 2πr
2πr = 30π inches
Area = πr² = π*15*15 = 225π square inches
Answer:
x=0.5355 or x=-6.5355
First step is to: Isolate the constant term by adding 7 to both sides
Step-by-step explanation:
We want to solve this equation:
On observation, the trinomial is not factorizable so we use the Completing the square method.
Step 1: Isolate the constant term by adding 7 to both sides
Step 2: Divide the equation all through by the coefficient of which is 2.
Step 3: Divide the coefficient of x by 2, square it and add it to both sides.
Coefficient of x=6
Divided by 2=3
Square of 3=
Therefore, we have:
Step 4: Write the Left Hand side in the form
Step 5: Take the square root of both sides and solve for x
