a helicopter hovers over a park. the pilot sees a person who is looking for their dog. the angle of depression from the pilot to the dog is 63 degrees and the angle of depression from the pilot to the owner of the dog is 48 degrees. if the dog is 70 feet ahead of the owner, and the helicopter flies over the line joining them, how high is the helicopter? round your answer to the nearest tenth of a foot

The pilot is 179 ft high

Step-by-step explanation:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
