Answer 1

Explanation:

sin(D) =
`\frac{\text{Opposite side}}{\text{Hypotenuse}}`

=
`(7)/(14)`

=
`(1)/(2)`

= 0.5

cos(D) =
`\frac{\text{Adjacent side}}{\text{Hypotenuse}}`

=
`(12.124)/(14)`

= 0.866

tanD =
`\frac{\text{Opposite side}}{\text{Adjacent side}}`

=
`(7)/(12.124)`

= 0.577

Since, sinE = cosD

Therefore, sinE = 0.866

Since, cosE = sinD

Therefore, cosE = 0.5

Since, tanE =
`\frac{\text{Opposite side}}{\text{Adjacent side}}`

=
`(12.124)/(7)`

= 1.732
