An air balloon is connected to the ground by a cable with a length of 200 meters inclined at a 60 degree angle. How high off the ground is the air balloon? (please show your work)

If you answer 2+2 you will get over 80 points

Me find the value of x each figure.

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
