Step-by-step explanation:
law of cosines states that ![c^{2} =a^{2} +b^{2} -2ab (cos(\alpha ))](https://tex.z-dn.net/?f=c%5E%7B2%7D%20%3Da%5E%7B2%7D%20%2Bb%5E%7B2%7D%20-2ab%20%28cos%28%5Calpha%20%29%29)
so we know that a = 7, b = 4, and alpha would be 135 degrees, so just plugging it in gets us 49+16-2*7*4*(-0.707) = 65 + 39.59 = 104.59
