Please help me thanks please

Missing side is 15 in

area 150 in^2

Step-by-step explanation:

x = √ (25^2 - 20^2)

x = √ 625 - 400

x = √ 225

x = 15

area = bh/2

area = (20 * 15) /2

area = 300 / 2

area = 150

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
