Use the figure and the value given below to answer the follo

Use the figure and the value given below to answer the following questions. Assume A = 4. Express x in terms of trigonometric ratios of theta. x = Express y in terms of trigonometric ratios of theta. y =

Solution

a)tan=opposite side/adjacent side

tan=x/A

tan=x/4

x=4tan

b)cos=adjacent side /hypotenuse

cos=A/y

cos=4/y

y=4/cos

y=4sec
