1 Which side is not involved in the question? Opposite Adjacent Hypotenuse 1 So we are using the opposite side and the hypotenuse, which trig ratio uses those 2 sides? Sin Cos Tan 1 Complete the working out: sin Given sin θ = o = O H 1 Get y by itself by multiplying 12 to the other side Given × sin 50 = y 1 Given 12 × sin 50 = y Complete on your calculator and choose the correct answer. y = 8.5 y = 9.2 y = 9.9 2 Which side is not involved in the question? Opposite Adjacent Hypotenuse 2 So we are using the opposite sideand the adjacent side, which trig ratiouses those 2 sides? Sin Cos Tan 2 Complete the working out: tan Given o = 2 Get v by itself by multiplying 25to the other side Given × tan 62 = v 2 Given 25 × tan 62 = v Complete on your calculator and choose the correct answer. v = 47.0 v = 47.1 v = 47.2 |
