The answer is 55 degrees.
In light of the fact that a 22-foot ladder's top rests against an 18-foot wall.
Together, the floor, the wall, and the ladder form a right angle triangle .with the ladder serving as the hypotenuse.
Thus, a right triangle with a hypotenuse of 22 feet is formed.
When the wall's side equals 18.
The angle that the ladder forms with the ground is the necessary angle.
Therefore, if x is the angle, we have
This allows us to determine the angle X.
X = 18/22 sin inverse
X=54.9
Justify it with X=55 degrees.
What is right angle triangle ?
- A right triangle is a triangle in which one of the angles is at a right angle or two of the sides are perpendicular, or more formally, an orthogonal triangle, formerly known as a rectangle triangle.
- The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
