Question 169392: Will you please help. I'm stuck.
Solve triangle ABC if C=90 degrees, B=20 degrees, and b=10. Round measures of sides to the nearest tenth and measures of angles to the nearest degree. I have to show my work, and don't understand how to do this.
Thank you

Since it's a triangle you know that,

I'm assuming that b is the side across from angle B.
Since one of the angle is 90 degrees, it's a right triangle and

Also from trig,

and from above,

Angles to the nearest degree,
A=70
B=20
C=90
Sides to the nearest tenth,
a=27.5
b=10
c=29.2
