Question

Solving Problems with Right Triangles

Answer 1

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?

Answer 2

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

Answer 3

like which angles we should use

Answer 4

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

Answer 5

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.

Answer 6

yeah i get it

Answer 7

so we have an angle, hypotenuse, and adjacent

Answer 8

but how can we find M

Answer 9

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

Answer 10

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

Answer 11

thank youu!
