Calculate 3208

Calculate the size of the sides and angles of the triangle ABC, if you know vc = 28, α = 51 ° 19 ', β = 67 ° 38'.

Correct answer:

a =  30.2779
b =  35.8693
c =  33.9406
C =  61.05 °

Step-by-step explanation:

h=28 a=h/sin(67+38/60)=28/sin(67+38/60)=30.2779
c1=b2h2=35.8693228222.4189 c2=a2h2=30.2779228211.5217 c=c1+c2=22.4189+11.5217=33.9406
