'Calculate 6224

Right triangle. Given: side c = 15.8 and angle alpha = 73°10'. Calculate side a, b, angle beta, and an area.

Correct answer:

a =  15.123
b =  4.5755
B =  16.8333 °
S =  34.5976

Step-by-step explanation:

c=15.8 A=73+6010=6073 60+6010=604380+6010=604380+10=604390=6439=736173.1667   sin A = ca a=c sin(A° rad)=c sin(A° 180π )=15.8 sin(73.166666666667° 1803.1415926 )=15.123
b=c2a2=15.8215.1232=4.5755
B=90A=906439=690 66439=65406439=6540439=6101=16.8333=16°50
S=2a b=215.123 4.5755=34.5976
