Answer:
slope of a line m : 0
Equation of line : y=- 9
Step-by-step explanation:
P1 : (X1 , Y1 ) (-3 , -9)
P2 : (X2 , Y2) (5 , -9)
Slope of line (m) is caculated as ,
m = ( y2-y1)/(x2 - x1)
m = (-9 - (-9))/(5 - (-3))
m = 0
equation of line : y = mx+b
using P1 (-3 , -9)
= > (-9) = (0)(-3) + b
= > -9 = b
hence b = -9
equation of Line is
y = -9
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.
