No , because if you were to add 4+6 in the second equation you’ll get 10 then subtract the 4 on the right side that would give you. 2d + 6 = 5. So 2d + 4 = 5 is not the same as 2d + 6 = 5
Answer:
This is an equation of tangent and normal to the curve
Answer:
Angle of elevation of the airplane = 17.46 degrees
Step-by-step explanation:
From the picture attached,
An airplane is flying at an altitude of 1500 ft at point A.
Runway starts from point B from which distance of the airplane is 5000 ft.
Now we apply sine rule in the given triangle ABC to measure the angle θ.
sinθ =
sinθ =
=
degrees
The answer would be 0, -1,-5,-7
