Right angled triangle 3

Side b = 1.5, hypotenuse angle A = 70 degrees, Angle B = 20 degrees. Find the length of its unknown sides.

Correct answer:

c =  4.3857
a =  4.1212

Step-by-step explanation:

A=70  B=20° rad=20° 180π =20° 1803.1415926 =0.34907=π/9 b=1.5  sin B = cb  c=b/sin(B)=1.5/sin0.3491=4.3857
