The descent rate is 7 feet/second. the subs elevation would be 7 x 10(60) which is 7x 600the sub's elevation would therefore be 4,200 feet below sea level
<span>The answer is the coefficient of the x-tem of the trinomial</span>
Hello,
Let y=sin^(-1)(12/13.
==>sin y=12/13
==>cos y=√(1-(12/13)²)=√(25/169)=5/13
Answer 5/13
If we know just two sides of a triangle, we can find<span> the </span>measure<span> of the</span>angles<span>. Step 1: Choose which trig </span>ratio<span> to use. We need to determine how the two sides we know the length of are related to </span>angle<span> A. The 4 in. side is adjacent to A and the 7 in.</span>
