We know that
applying the law of sines
50/sin 40=60/sin x
50*sin x=60*sin 40
sin x=[60*sin 40]/50
sin x=0.7713
x=arc sin (0.7713)----> x=50.47°--------> x=50.5°
the answer is
x=50.5 °

Answer:
Well you can either straight up subtract from the total degrees of a triangle using the sum of both of the given angles, which would equal x, or you can make an equation. I’ll do both.
180-78-51=51, x=51
78+51+x=180
129+x=180
x=180-129
x=51
