Unfortunately, I do not fully comprehend this explanation. My question is why 33 degrees is not the correct angle for Theta.ehild said:The tension in the cables keep the post in vertical position. Its top point can not move sideways, the horizontal components of the tensions balance each other.
The vertical components do not need to be equal, as they are balanced by the force from the ground.
You calculated theta from the condition that the vertical components of the tensions are equal, which is wrong .Ryan Lau said:Unfortunately, I do not fully comprehend this explanation. My question is why 33 degrees is not the correct angle for Theta.

Angles are geometric figures formed by two rays or lines meeting at a point. They are typically measured in degrees, with a full circle being 360 degrees.
The measure of an angle can be calculated using the formula: angle = arc length / radius. This formula applies to all types of angles, including acute, right, and obtuse angles.
There are four types of angles: acute, right, obtuse, and straight. Acute angles measure less than 90 degrees, right angles measure exactly 90 degrees, obtuse angles measure between 90 and 180 degrees, and straight angles measure exactly 180 degrees.
The Pythagorean Theorem states that for a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This theorem can be used to calculate angles in a right triangle by finding the inverse trigonometric function of the sides.
Trigonometric functions, such as sine, cosine, and tangent, can be used to calculate angles in a right triangle. These functions involve using the ratios of the sides of the triangle to find the measure of the angle. For example, the sine function is equal to the opposite side divided by the hypotenuse.
