Answer:
x = 15.4
Step-by-step explanation:
Because this is a right triangle, you can use the pythagorean theorem to find the length of the hypotenuse. the theorem is a^2 + b^2 = c^2
 so
9^2 + 12.5^2 = c^2 
solving this will give you 15.4

Step-by-step explanation:
0.4 x + 3.9 = 5.7
 hope 0.4 x = 5.78 - 3.9
