The answers to the missing angle is 40°
Answer:
$26
Step-by-step explanation:
<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>
Answer:
10/33 there 33 chocolates in the bag but only 10 are dark chocolate
Step-by-step explanation:

So in total 8+4 would be 12 spaces. Rmr when you calculate distance you can’t subtract a negative. A negative really means backwards not destroyed in terms of distance. So total is 12 spaces.
2/3 of 12 is 8. Think of it like this
2/3=x/12
You could do butterfly or you could realize 3x4=12
So 2x4=8 would be proportional to the ratio we are looking for.
