Solve Triangle DEF. - Math

Answer:
[tex]p = 52.942259755149776[/tex]
Step-by-step explanation:
This is basic trigonometry.
[tex] \cos(39) = \frac{e}{22} [/tex]
[tex]e = \cos(39) \times 22[/tex]
[tex] \sin(39) = \frac{d}{22} [/tex]
[tex]d = \sin(39) \times 22[/tex]
And finally perimeter (p):
[tex]p = 22 + e+ d[/tex]
