Lena [83]

Step-by-step explanation:

Use the method of TOA CAH SOH.

$tan(51.3) = \frac{opp}{adj} \\ \tan(51.3) = \frac{u}{4} \\ u = 4 \tan(51.3)$

$cos(51.3) = \frac{adj}{hypo} \\ \cos(51.3) = \frac{4}{v} \\ v \cos(51.3) = 4 \\ v = \frac{4}{ \cos(51.3) }$

Perimeter of triangle = Sum of all sides =

$u \: + \: v + 4$
