Answer:
![\fbox {Perimeter = 37.92}](https://img.qammunity.org/2023/formulas/mathematics/high-school/zeecdypqmnsynkv2gntscdzw1sxdtp9kt8.png)
Explanation:
Finding the missing side :
⇒ Take the tan value of the listed angle
⇒ tan 60° = √3 = 6/x
⇒ x = 6/√3 × √3/√3 = 2√3 = 2(1.73) = 3.46
Solving :
⇒ Perimeter = 10 + 2(6 + 3.46)
⇒ Perimeter = 10 + 2(9.46)
⇒ Perimeter = 19 + 18.92
⇒ Perimeter = 37.92
