Answer:

12∠x∠16

Step-by-step explanation:

For the triangle to be acute,a²+b²+c²,

Where c is the largest side of the triangle.  

Hence, we must say x²+(x+4)²≥20²,  

or after simplifying, x²+4x-192≥0 or (x+16)(x-12)≥0

Since x must have positive values only, x≥12

Therefore, for the triangle to be acute,we must have 12≤x≤16.
