Multiple Choice

Find the missing side lengths in the triangle. Give the exact answer and then an approximation to two decimal places, when appropriate.

A) $x = 10 \sqrt { 3 } \approx 17.35 , h = 20$
B) $x = 10 \sqrt { 3 } \approx 17.32 , h = 20$
C) $x = 20 , h = 10 \sqrt { 3 } \approx 17.32$
D) $x = 21 , h = 10 \sqrt { 3 } \approx 17.35$
E) $x = 10 \sqrt { 3 } \approx 17.32 , h = 21$
