Answer:
8 cm , 9cm
Step-by-step explanation:
sum of any two sides >third side
difference of any two sides<third side
only 8 cm and 9 cm satisfies it
8+9=17>13
9-8=1<13
Answer:
D.
Step-by-step explanation:
The polynomial cannot be factored with rational numbers.
Answer:
x = 13
Step-by-step explanation:
5x + 12x - 41 = 180
17x = 221
x = 13
Answer:
Area of shaded region is .
Step-by-step explanation:
We are attaching the diagram for your reference.
Given:
AB = 10
BC = 2
We need to find the Area of the shaded region.
Area of the shaded region is equal to sum of Area of triangle ABE and Area of triangle CDE.
Now first we will find area of both the triangles.
Now we know that Area of triangle is half times base times height.
In Δ ABE,
base AB = 10 (given)
Since given point E lies half way between sides AB and CD and halfway between sides AD and BC.
So height h is,
height h =
Area of Δ ABE =
In Δ CDE,
base CD = AB = 10 (given it is a rectangle and opposite side of rectangle are equal)
Since given point E lies half way between sides AB and CD and halfway between sides AD and BC.
So height h is,
height h =
Area of Δ CDE =
Now Area of shaded region = Area of Δ ABE + Area of Δ CDE =
Hence Area of shaded region is .
