Find the value. Please

The cosine ratio is adjacent leg divided by the hypotenuse.
The hypotenuse in a right triangle is the longest side and it is opposite the right angle.
An adjacent leg is the side that has an endpoint that is at the vertex of the angle and the other endpoint is at the vertex of the right angle.

cos A = $\frac{12}{20} = \frac{3*4}{5*4} = \frac{3}{5}$
ANSWER: $cosA= \frac{3}{5}$

Would anyone be willing to help me with geometry?

From the second and third steps, we know that m∠TUV = m∠1 + m∠2. We also know that m∠XWV = m∠3 + m∠4. Since ∠TUV and ∠XMV both measure 90°, we can set their measures equal to each other:

m∠TUV = m∠XMV

or equivalently:

m∠1 + m∠2 = m∠3 + m∠4

Next, we can use the fact that ∠1 ≅ ∠3 to say that m∠1 = m∠3, while allows us to replace one with the other. Here, we'll replace m∠3 with m∠1:

m∠1 + m∠2 = m∠1 + m∠4

Subtracting m∠1 from either side:

m∠2 = m∠4, which implies that ∠2 ≅ ∠4, as we wanted to show.
