Answer:

3 is the missing answer.

Step-by-step explanation:

7 * 3 = ( _ * 3) + ( 4 * 3)

21 = ( _ * 3) + 12 -Multiply 4 * 3 and 7 * 3

9 = _ * 3 -Divide both sides by 3

3 = missing number

SAS similarity. the angle degree is the same. if you multiply 14 and 8 by a factor of 7 you get 98 and 56 which means the triangle have the same ratio making them similar. because of this ratio it makes the side similar therefore being a SAS similarity because the angle is between the sides.
