  51

Step-by-step explanation:

The exterior angle is equal to the sum of the remote interior angles.

  71° = 20° + x°

  51 = x . . . . . . . . . divide by °, subtract 20

Additional comment

Consider the missing interior angle of the triangle. It is 180° - 71°. It is also 180° -20° -x°. Equating these values and rearranging, we get ...

  71° = 20° + x°

In short, supplements of the same angle are congruent. This relationship can save you the unnecessary work of figuring out the missing interior angle.

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 ..
