Answer:
x = 33.8°
Step-by-step explanation:
The resulting diagram we have is a right triangle. To find x, apply trigonometric function.
Reference angle = x
Opposite = 116
Adjacent = 173
Apply TOA:
Tan x = Opp/Adj



x = 33.8° (nearest tenth)
 
        
             
        
        
        
Answer:
Rotations, reflections and translations.
Step-by-step explanation:
Rotations, reflections and translations are transformations that preserve the both the angle measurements and the lengths of the sides, so congruence is preserved.
Dilations are transformations that keep the angle measurements, but the side lengths change, so the transformation is similar, not congruent.
