Answer:
38.6598 ° or 38.66 °
Step-by-step explanation:
Sides:
a = 4 cm
b = 6.40312 cm
c = 5 cm
Angles:
A = 38.6598 °
B = 90 °
C = 51.3402 °
Other:
P = 15.4031 cm
s = 7.70156 cm
K = 10 cm2
r = 1.29844 cm
R = 3.20156 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
