If the value of θ is 46.4°. Then the value of the cosine of θ will be 20/29.
<h3>What is trigonometry?</h3>
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The value of sine of θ is 21/29.
Then the value of θ will be
sin θ = 21/29
θ = sin⁻¹(21 / 29)
θ = 46.4°
Then the value of the cosine of θ will be
cos θ = cos 46.4°
cos θ = 20/29

After checking with each triplet whether they form a Pythagorean triplet, we find that D) [10, 24, 26] is the only one that applies with the triplet.
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
Since you know:
m = -2
b = 5 Substitute/plug it into the equation
y = mx + b
y = -2x + 5
When the coefficient of eˣ, A, is:
-1 < A < 1
