Calculate 6219

Right triangle. Given: page b = 15.8 angle alpha = 15 ° 11` Calculate the page
a, c, beta angle, and area

Correct answer:

c =  16.3715
a =  4.2878
B =  74.8167 °
S =  33.8739

Step-by-step explanation:

b=15.8 A=15+6011=60911=15601115.1833   cos(A)=cb  c=b/cos(A° rad)=b/cos(A° 180π )=15.8/cos(15.183333333333° 1803.1415926 )=16.371=16.3715
a=c2b2=16.3715215.82=4.2878
B=90A=9015.1833=74.8167=74°49
S=2a b=24.2878 15.8=33.8739
