In △ ABC, ∠ C = 90 °, if B = m, ∠ a = 30 °, then a =, C=

This is a junior high school topic? Even if I just learned it today, it should be very simple. I won't listen to it in class
∵∠C=90°,b=m,∠A=30°
Let a = x, then C = 2x,
From C & sup2; = A & sup2; + B & sup2
4x²=x²+m²
∴x²=m²/3
x=(√3/3)m
∴a=(√3/3)m
c==(2√3/3)m
