$\text{The value of }\cos \angle B=\frac{12}{13}$

Step-by-step explanation:

Given a right angled triangle BAC in which

AB= 12 units, BC=13 units, AC = 5 units.

we have to find the value of cos B.

By trigonometric ratios,

$\cos x=\frac{Base}{Hypotenuse}$

∴ $\cos \angle B= \frac{AB}{BC}$

$\cos \angle B=\frac{12}{13}$

Option B is correct

Step-by-step explanation:

The slope of the line of best fit should be around:

(18-15)/(16-10) = 0.5

And

The y-intercept would be less than 15

Therefore, option C is the most suitable option
