$a = c = 32 units$ $a = c = 32 " units"$

$ˆ A = \frac{π}{12}, ˆ C = \frac{π}{12}, c = 32$ $hat A = pi/12, hat C = pi/12, c = 32$

Since $ˆ A = ˆ C, it's an isosceles triangle and side c = a$ $hat A = hat C, " it's an isosceles triangle and side c = a"$

Hence, $a = c = 32 units$ $a = c = 32 " units"$

A triangle has sides A, B, and C. The angle between sides A and B is π12pi/12. If side C has a length of 3232 and the angle between sides B and C is π12pi/12, what is the length of side A?
