Answer:

y = 3

Step-by-step explanation:

The left side has to equal the right side

10 = 2y+4

Subtract 4 from each side

10-4 = 2y+4-4

6 = 2y

Divide each side by 2

6/2 = 2y/2

3 = y

Answer:

y = 3.

Step-by-step explanation:

Since we know that this is a rectangle, this means that there are two pairs of parallel and congruent sides.

If the width of the rectangle equals 10, then 2y + 4 must equal 10.

Solve for 'y':

10 = 2y + 4

6 = 2y

y = 3.

Four to the second power is just 4^2 which is equal to 16 (4*4 = 16)
Four the the eight power is just 4^8 which is equal to 65536 (4*4*4*4*4*4*4*4 = 65536)

$\frac{sin(A)}{a} = \frac{sin(B)}{b}$

$\frac{sin(90)}{14.6} = \frac{sin(45)}{x}$

Cross multiply

x*sin(90) = 14.6sin(45)

x = 14.6sin(45)
