Answer:The answer is actually 13.6.
So the question would make sense with the picture of it . so here it is. so first you find the bottom triangle which is 5² + 12² = DG² That is equal to 25 + 144 = 169. Then you find the square root of 169 and that's the answer for the bottom triangle.. √169 = 13. So since I figured out the line segment DG I solve the triangle ADG. AD = 4² or 16, Dg = 13² (The bottom triangles hypotenuse) or 169. So 169 + 16 = 185 (or AG) and then find the square root of 185 and using a calculator, I get 13.6014705087 which is rounded to 13.6. So the answer for AG is C. 13.6. Please mark the Brainliest.
