'Calculate 6224

Right triangle. Given: page c = 15.8 and angle alpha = 73 ° 10 'Calculate page 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=6439=736173.1667   sinA=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=9073.1667=16.8333=16°50
S=2a b=215.123 4.5755=34.5976
