Answer 1

Answer:

$33+11\sqrt{3}$.

Step-by-step explanation:

sin(30º) = 0,5

$\frac{1}{2} = \frac{b}{c} \\ b = \frac{c}{2} \\ b = 11.$

$c^2=a^2+b^2 \\ a^2 = c^2-b^2\\ a^2=22^2-11^2 \\ a^2 = 484 - 121 = 363 \\ a = \sqrt{363} \\ \sqrt{363} = \sqrt{3*121} = 11\sqrt{3}.$

$P = a+b+c \\ P = 11+22+11\sqrt{3} \\ P = 33+ 11\sqrt{3}.$
