Well, the sum of the angles in a triangle equals 180 degrees.
So you do 180 minus the two angles to get the third angle.
180 - 78.4 - 57.2 = 44.4
44.4 degrees

To find AC, use the law of sines.
Length A / sin (angle a) = length b / sin(angle b)

Answer: 15

Step-by-step explanation:

Lets name the missing point as "x"

8^2 + x^2 = 17^2

=> 64 + x^2 = 289

=> x^2 = 289 - 64

=> x^2 = 225

=> x = 15
