ok so since it deals with right triangles, we can use SOH CAH TOA. which one should we use that includes both right and M angle?

OpenStudy (anonymous):

sorry, ignore that "includes right angle part"...

OpenStudy (anonymous):

like which angles we should use

OpenStudy (anonymous):

well, we need to use the angle M to start off with.

OpenStudy (anonymous):

then, from angle M, we have two side lengths: one that is the hypotenuse and one that is adjacent (beside, or touching) to angle M.

OpenStudy (anonymous):

yeah i get it

OpenStudy (anonymous):

so we have an angle, hypotenuse, and adjacent

OpenStudy (anonymous):

but how can we find M

OpenStudy (anonymous):

i'm telling you how. from the info i gave you, do we use soh, cah or toa?

OpenStudy (anonymous):

ok, so we use CAH because it includes both adjacent and hypotenuse. so cosine (angle) = A/H cosine (degrees)= 40/76 cos -1(40/76)= answer

thank youu!
