PLEASE ANSWER ASAP TY In triangle ABC below, BD is the altitude. Find the length of DC. Leave your answer in
simplified radical form.

Step-by-step explanation:

Step 1: Find AB Use Pythagoras Theorem

AB =

Step 2: Find the Area of the triangle ABC

Area = =

Step 3: Find BD. Use the area of the triangle above

Area =

We already known the Area and AC so, we just plug all the number in

BD = =   =

Step 4: Find DC. Use Pythagoras Theorem of the triangle BDC

DC = = =  

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz
