Answer:
x = 50°
Step-by-step explanation:
Here we are given the hypotenuse and the adjacent side (to the x angle)
Therefore we able to calculate cosinus
cos = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{50}{78}[/tex] = 0,6410...
From the table, we see that cos = 0,6410... is closest to the angle value of 50°
Therefore x = 50°
