Given:

The figure of a right angle triangle.

To find:

The value of x to the nearest hundredth.

Solution:

In a right angle triangle,

\cos \theta=\dfrac{Base}{Hypotenuse}

Using the above trigonometric ratio for the given triangle, we get

\cos 46^\circ=\dfrac{x}{8}

0.6947=\dfrac{x}{8}

0.6947\times 8=x

5.5576=x

Approximate the value to the nearest hundredth.

x\approx 5.56

Therefore, the value of x is 5.56 units.

Here, y = -15 with x = -20
LCM of 15 & 20 is 60, so divide 15 & 20 from 60, 
60/15 = 4 & 60/20 = 3

Now, multiply the results with intial values, 
4y = 3x
y = 3/4 x

When y = 12, 
x = 12 * 4/3
x = 48 / 3
x = 16

In short, Your Answer would be 16

Hope this helps!
