Question

Will award points- im currently using cos, sin and tan

Answer 1

w = 9.82

x = 66.73

Explanation:

By applying tangent rule in triangle ABD,

tan(81°) =
`\frac{\text{Opposite side}}{\text{Adjacent side}}`

6.31 =
`(62)/(w)`

w =
`(62)/(6.31)`

w = 9.82

Similarly,

tan(39°) =
`\frac{\text{Opposite side}}{\text{Adjacent side}}`

0.81 =
`(62)/((x+w))`

0.81 =
`(62)/(9.83+x)`

9.82 + x =
`(62)/(0.81)`

x = 76.56 - 9.82

x = 66.74
