The figure suggests that the two sub-triangle are similar, because they are both right and the angle at the top is the same.

If that is the case, we can claim that the correspondent sides are in proportion:

$6\div 9 = x \div 8$

Solving for x we have

$x = \dfrac{6\cdot 8}{9}=\dfrac{48}{9}=\dfrac{16}{3}$

2y - 3/5 = 1/2

Add 3/5 to both sides.

2y = 1/2 + 3/5

Let's make the two fractions have common denominators.
Multiply 1/2 by 5/5 and 3/5 by 2/2.
1/2 * 5/5 = 5/10
3/5 * 2/2 = 6/10

2y = 5/10 + 6/10

Add the two fractions.

2y = 11/10

Divide both sides by 2.

11/10 ÷ 2
Use the Keep, Change, Flip method.
Keep 11/10, change ÷ to ×, and flip the 2 (reciprocal).
11/10 × 1/2 = 11/20

y = 11/20

Answer:option A is the correct answer.

Step-by-step explanation:

The given triangle UVW is a right angle triangle. This is because one of its angles is 90 degrees. The sum of the two other angles is 180. To determine Cos U, we will apply trigonometric ratio.

Cos U = adjacent side/ hypotenuse.

Looking at the triangle with C as the reference angle,

Adjacent side = 12

Hypotenuse( always the longest side of the triangle) = 13

Therefore,

Cos U = 12/13
