As shown in the accompanying diagram, a ship is headed directly te ard a coastline formed by a vertical eliff BC. 70 meters high. At point A, the angle of elevation from the ship to B, top of the cliff, its 23°. A few minutes later a point D, the angle of elevation increased to the nearest meter, what is the distance between the ship's itions at the two sightings?

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

i dont know

step-by-step explanation:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
