Pls will give brainliest and all p.s u can zoom in if u cant see plss

In right ∆abc shown below, the midpoint of hypotenuse ac is located at d and segment bd is drawn.if ab = 12 and bc = 16, then explain why bd = 10. hint: consider what you know about the diagonals of a rectangle.

Determine which expressions represent real numbers and which expressions represent complex number. asaaap! plis!
