Angle of elevation.
<span>On the first, the 456 is the opposite leg and the 837 is the adjacent to the angle of elevation so use tangent (from soh cah toa); x = the angle measure </span>
<span>tan x = 456/837 </span>
<span>inverse tan (456/837) = x so do that on your calculator (be sure it is in degree mode). </span>
<span>Then for Ramsey, 1453 is opposite leg and 2960 is adjacent so you have tan x = 1453/2960 and do like the first one.</span>
Answer:tiz x
Step-by-step explanation:
The answer is the last one. If and only if means that both things are the result of one another. for example... If it's valentines day, it is February but if it's February, it's not necessarily Valentines day.
