Given the triangle below, what is sec ∡B?

OpenStudy (anonymous):

OpenStudy (anonymous):

hypotenuse/base

OpenStudy (anonymous):

so it'd be 7/4 ??

OpenStudy (anonymous):

no,base is AB

OpenStudy (anonymous):

it doesn't give me AB though..

OpenStudy (hezekieli):

I'm new to doing math in English, but do you mean the angle of B or the length of AB?

OpenStudy (anonymous):

would it be 4sqd33/33 or 7sqd33/33

OpenStudy (anonymous):

AB = root 49-16

OpenStudy (anonymous):

my options are 4sqd33/33 or 7sqd33/33

OpenStudy (hezekieli):

Yes. \[\sqrt{(7^{2}-4^{2})} = \sqrt{49-16} = \sqrt{33} \approx 5,74\]

OpenStudy (hezekieli):

I don't understand those options of yours :P

OpenStudy (anonymous):

i got it. it was 7 squared33/33
