Answer:
63.4°
Explanation:
The following data were obtained from the question:
Opposite = 6 cm
Adjacent = 3 cm
Angle x =? 
The value of angle x can be obtained as follow:
Tan x = Opposite/Adjacent 
Tan x = 6/3
Tan x = 2
Take the inverse of Tan. 
x = Tan¯¹ 2
x = 63.4°
Therefore, the value of angle x is 63.4°
