Answer:

$\frac{24}{25}$

Step-by-step explanation:

using the cosine ratio;

$\cos(\theta)= \frac{adjacent}{hypotenuse}$

From the question, the side of the right angle triangle that is adjacent to the measured <a,(i.e BAC) is AC=24 and the hypotenuse is AB=25

This implies that,

$cos(a)= \frac{24}{25}$

Answer:

B. (3, 2)

Step-by-step explanation:

Given vertices of triangle:

A(1, 2), B(3, 4), C(5, 0)

The centroid is found as the average of x- and y- coordinates of three vertices:

C = ((x₁ + x₂ + x₃)/3, (y₁ + y₂ + y₃)/3)

Substitute the coordinates into formula:

C = ((1 + 3 + 5)/3, (2 + 4 + 0)/3) = (3, 2)

Correct choice is B
