Right triangle

Calculate the length of the remaining two sides and the angles in the rectangular triangle ABC if a = 10 cm, angle alpha = 18°40'.

Correct answer:

A =  18.6667 °
B =  71.3333 °
C =  90 °
a =  10 cm
b =  29.6004 cm
c =  31.244 cm

Step-by-step explanation:

A=18+40/60=18.6667°=18°40
B=90A=9018.6667=71.3333°=71°20
C=90=90°
a=10=10 cm
c=a2+b2=102+29.60042=31.244 cm
