The sin A is equal to 12/13 and the tan (A) is equal to 12/5.

<h3>RIGHT TRIANGLE</h3>

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  The greatest side of a right triangle is called hypotenuse. And, the other two sides are called cathetus or legs.

The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.

The Pythagorean Theorem says: hypotenuse^2=(leg_1)^2+(leg_2)^2. And the main trigonometric ratios are:

sin(\beta )= \frac{opposite\;leg}{hypotenuse} \\ \\ cos(\beta )= \frac{adjacent\;leg}{hypotenuse} \\ \\ tan(\beta )= \frac{opposite\;leg}{adjacent\;leg} \\ \\

The question gives cos (A)=5/13. If cos (A) is represented by the quotient between the adjacent leg and the hypotenuse, you have:

adjacent leg=5

hypotenuse=13

Therefore, you can find the opposite leg of A from Pythagorean Theorem, see below.

hypotenuse^2=(leg_1)^2+(leg_2)^2\\ \\ 13^2=5^2+(leg_2)^2\\ \\ 169=25+(leg_2)^2\\ \\ 144=(leg_2)^2\\ \\ leg_2=12

Thus, the opposite leg is equal to 12. Now, you can find sin (A) since:

sin(A)= \frac{opposite\;leg}{hypotenuse}=\frac{12}{13}

Finally, you can find the tan (A) since:

tan(a )= \frac{opposite\;leg}{adjacent\;leg}=\frac{12}{5}

4). x/5 =8
     x = 40
5). 2x/3 = 12
     2x = 36
      x = 36/2 = 18
6). x + 26 =12
      x = 12 - 26 = -14
7).  8x + 1 = -23
      8x = -23 -1
      8x = -24
        x = -24/8 = -3
8). 2x + 5 =15
     2x = 15 - 5
     2x = 10
       x = 10/2 = 5
9). 3x - 1 = -29
     3x = -29 + 1
     3x = -28
       x = -28/3 Or 9.33
10). 8x - 12 = 53
       8x = 53 + 12
       8x = 65
        x = 65/8 Or 8.12
11). 4x + 7 = 25
       4x = 25 - 7
       4x = 18
        x =18/4 = 9/2 Or 4.5
