Two numbers have a average of 17. if one of the numbers is 11, what is the other number

Other number is 23

Step-by-step explanation:

Let the two numbers be x and y.

We have given that average of x and y is 17.

i.e

if one of the number is 11,

Then ,

or  (11 + y)/2 = 17

or 11 + y = 34

or y = 34 - 11

or y = 23

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..
