Find the angle of elevation of the plane
When it reaches 300 feet above the ground.

X=36.87°

Step-by-step explanation:

Tanx=opposite/adjacent

Tanx =300/400

Tanx=0.75

X=tan-¹(inverse)0.75

X=36.87°

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

angle addition postulate

2x=56
