Domain is x # 0
A case of a polynomial
6 units Foo
Explanation
Cause it’s just 6 units
<span> Sketch this, assuming the Earth is a sphere with radius R, so a plane slice through the periscope, ship and center of the Earth is a circle of radius R. Draw the lines out from the center (O) of the circle to point A at the top of the periscope and point B at the top of the ship. so that line AB is tangent to the circle at point C. That makes triangles OAC and OBC right triangles, each having the right angle at C. </span>
<span>From the problem, the lengths OA = R+5, OC = R, and OB=R+50. Label the lengths AC = p and BC= q, then use Pythagoras: </span>
<span>R² + p² = (R + 5)² </span>
<span>R² + q² = (R + 50)² </span>
<span>Solve those: </span>
<span>p² = (R + 5)² - R² = 10R - 25 </span>
<span>p = √(10R + 25) </span>
<span>q² = (R + 50)² - R² = 100R + 2500 </span>
<span>q = √(100R + 2500) </span>
<span>Find a good value for the radius R (in ft. units!) and calculate. The distance from periscope top to ship top is (p + q) feet. Convert that to miles for your answer.</span>
Ok here we go, I will go step-by-step:
So first we have to figure out what y is. we see that the angles outside y are 52 and 59, so we add those together and get 111. now we know whatever y is, it has to equal 180 when added to 111 because it is a straight line. Therefore, angle y is 69 degrees. Now, we also know the angles inside a triangle have to equal 180 when added together. we know two of them. They are 63 and 69. Add those together and we get 132. That means x has to equal 48, to make the inside angles equal 180. The answer is x=48
