please answer both....... it's urgent​

Answer 1

Answer:

D) parallelogram

don't know the answer of E)

Answer 2

Step-by-step explanation:

The ratio of the angles of a quadrilateral=2:7:2:7

Let they are 2x,7x,2x,7x

Their sum=2x+7x+2x+7x=18x

The sum of four angles in a quadrilateral=360°

=>18x=360°

=>x=360°/18

=>x=20°

=>2x=2(20°)=40°

7x=7(20°)=140°

The angles are 40°,140°,40°,140°

They are angles of a Parallelogram

option a

__________________________________

2)HCF of two numbers =48

Since 48 is their HCF then that is the factor of the two numbers

in that 2400 is divisible by 48

so the product of two numbers can be 2400

Option b

______________________________________

(-x)²+(-y)²

=>x²+y²
