Answers:
-the measure of the remaining leg is 21 multiplied by the square root of 3
-the angle opposite the side with length 21 units measures 30 degrees
Explanation:
i took the test, but also
if you multiply the shorter leg (21) by the square root of three, you get the longer leg length of 21 multiplied by the square root of 3
and if you draw it out with 21 as the shortest side, you can clearly see that the angle opposite the shortest side has to be 30 degrees because it’s too small to be 60 degrees.
