Right angled triangle 3

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

Correct answer:

c =  4.3857
a =  4.1212

Step-by-step explanation:

A=70 ° B=20° rad=20° π180 =20° 3.1415926180 =0.34907=π/9 b=1.5  sinB=bc  c=b/sin(B)=1.5/sin(0.3491)=4.3857
