I need help understanding this problem, any help is appreciated :)

B = 31.467 °

Step-by-step explanation:

Sides:

a = 13 cm

b = 9 cm

c = 17 cm

Angles:

A = 48.939 °

B = 31.467 °

C = 99.5941 °

Other:

P = 39 cm

s = 19.5 cm

K = 57.6818 cm2

r = 2.95804 cm

R = 8.62057 cm

Agenda:

A = angle A

B = angle B

C = angle C

a = side a

b = side b

c = side c

P = perimeter

s = semi-perimeter

K = area

r = radius of inscribed circle

R = radius of circumscribed circle

Formula: SSS is Side, Side, Side

Given the sizes of the 3 sides, you can calculate the sizes of all 3 angles in the triangle.  Use The Law of Cosines to solve for the angles.  You could also use the Sum of Angles Rule to find the final angle once you know 2 of them.

man its nopq i just guessed and got it right so uhh
