Me find the measure to side a and the process to solve the problem you appreciate it : )

a =12

Step-by-step explanation:

sin theta = opposite side / hypotenuse

sin 29 = a /25

Multiply each side by 25

25 sin 29 = a/25 *25

25 sin 29 =a

12.12024051 =a

To the nearest whole number

12 =a

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
