+128731 What is the answer to this?: cos43=15/b
Well...let's just "solve" for b. Multiply both sides by b and divide both sides by cos43. This gives us
b = 15 / cos(43).
Technically, the "43" represents 43 "radians," but I have a feeling that we're dealing with degrees, so I'm gonna' stick a little degree symbol on it !! (My former trig teacher used to become "unglued" if someone didn't specify "degrees!!!!") So we have...
b = 15 / cos(43°) ≈ 20.5
And there's "b"
