Akite on a 160-foot string is caught on a pole. when the full length of the string is stretched in a straight line to the ground, it touches the ground a distance of 50 feet from the bottom of the pole. the string forms an angle of ° with the ground when it is stretched like this.

Step-by-step explanation:

The string, pole, and ground form a right triangle.  The hypotenuse of this triangle is 160 feet.  The base of the triangle is 50 feet.  The angle adjacent to the base can be found with cosine:

cos x = 50 / 160

x = acos(50 / 160)

x ≈ 72°

72°

:)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
