From a plane flying due east at 270 m above sea level, the angles of depression of two ships sailing due east measure 35 and 25°
How far apart are the ships?​

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
