The answer is 1463 because if you add 677 and 786 it equals 1463.

To make sure it is 1463, subtract 786 from 1463 and see if the difference is 677.

Hope this helps!

Answer:

D 2.14

Step-by-step explanation:

The lengths of interest are the hypotenuses of the respective triangles. We are given the angle and the opposite side, so the sine relation is of interest.

Sin = Opposite/Hypotenuse

sin(34°) = AC/AB ⇒ AB = AC/sin(34°)

sin(53°) = AC/AD ⇒ AD = AC/sin(53°)

The desired difference in lengths is ...

AB -AD = AC(1/sin(34°) -1/sin(53°)) = 4(1.78829 -1.25214) ≈ 2.1446

The difference in lengths is about 2.14 units.
