Answer:
K = 13.15 cm^2
Step-by-step explanation:
Sides:
a = 8 cm
b = 3.75631 cm
c = 7 cm
Angles:
A = 90.9699 °
B = 28 °
C = 61.0301 °
Other:
P = 18.7563 cm
s = 9.37816 cm
K = 13.1452 cm^2
r = 1.40168 cm
R = 4.00057 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
