Right triangle

A right triangle ABC is given, c is a hypotenuse. Find the length of the sides a, b, the angle beta if c = 5 and angle alfa = A = 35 degrees.

Correct result:

a =  2.8679
b =  4.0958
B =  55 °

Solution:

c=5 A=35 sinA=a/c  a=c sinA=c sin35 =5 sin35 =5 0.573576=2.868=2.8679
cosA=b/c b=c cosA=c cos35 =5 cos35 =5 0.819152=4.09576=4.0958   Verifying Solution:  b1=c2a2=522.867924.0958
B=90A=9035=55
