Calculate the missing length,AC. (w.drawing)

OpenStudy (shelby1290):

|dw:1401359862957:dw|

OpenStudy (neer2890):

BD =48 m or 50 m

OpenStudy (shelby1290):

yes i believe that's right

OpenStudy (shelby1290):

so, do solve this problem will i be needed Pythagorean theorem?

OpenStudy (shelby1290):

*to

OpenStudy (shelby1290):

needing*

OpenStudy (neer2890):

BD should have one value either 48 or50. confirm that

OpenStudy (shelby1290):

bd=48

OpenStudy (shelby1290):

ad=50

OpenStudy (shelby1290):

and dc is 73

OpenStudy (neer2890):

use pythagorus theorem to find BC now if angle CBD is 90 then angle ABD must also be90 again use pythagorus theorem to find AB. add AB and BC

OpenStudy (shelby1290):

@neer2890 the question says that i need to find the missing length, AC

OpenStudy (neer2890):

so AB+ BC=AC itself

OpenStudy (shelby1290):

wait can you please explain to me again how to get AB and BC
