|AC|
------ = tan 25 deg, so |AC| = 8.6 tan 25 deg
8.6 8.6 (0.466) = 4.01 units (answer)
slope of a line that is perpendicular to the line y=-3x is 1/3
What is slope of line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. where "m" represents a line's slope. So, the slope of a line is tanθ.
y=-3x
tanθ=slope = y/x= -3
Slope(M) of this equation is -3
Let the slope of its perpendicular line is m
As we know that the product of the slopes of perpendicular lines is -1
so,
M*m =-1
-3 * m= -1
m=1/3

Answer:
11,700cm²
Step-by-step explanation:
Area of the triangle = 1/2*JK sin<I
Given
J = 800cm
K = 240cm
<I = 173 degrees
Substitute
Area of the triangle = 1/2 * 800 * 240 sin 173
Area of the triangle = 400 * 240sin 173
Area of the triangle = 400 * 29.25
Area of the triangle = 11,699.5
Area of the triangle to the nearest square centimeter is 11,700cm²
