The measure of the value of x is 70.52 degrees.
Given
A 12-foot ladder is placed 4 feet away from a house as shown.
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards.
<h3>What is cos angle?</h3>
The cos theta is defined as the ratio of the side adjacent to the angle and the hypotenuse.
The following formula is used to calculate the value of x;
Where the side adjacent to angle = 4 and hypotenuse is 12.
Substitute all the values in the formula;
Hence, the measure of the value of x is 70.52 degrees.
