(1) ∠ ACB = 90, CD is the midline on the hypotenuse AB,

∴CD=BD，

∴∠B=∠BCD，

∵AE⊥CD，

∴∠CAH+∠ACH=90，

∠ ACB = 90 degrees

∴∠BCD+∠ACH=90

∴∠B=∠BCD=∠CAH, that is ∠B=∠CAH,

AH = 2CH，

∴ AC=5CH comes from Pythagorean theorem,

∴CH:AC= 1:5，

∴sinb=55；

(2)∫sinB = 55，

∴AC:AB= 1:5，

∴AC=2.

∠∠CAH =∠B，

∴sin∠CAH=sinB=55= 15，
