I believe you have to multiply
Answer:
108°
Step-by-step explanation:
Angle 1 = Angle 2
Vertically opposite angles
Angle 2 = Angle 3 = 108
Corresponding angles
You answer is 152
Step by step:
Divide it into 2 rectangles
1st rectangle 10x8=80
2nd rectangle 12x6=72
80+72=152
For the element to be congruent only rotations, reflections or translations are allowed to be applied
1)
(x, y) → (x, –y)=reflection
(x, y) → (x + 5, y)=translation
(x, y) → (–x, y)=reflection
->is congruent
2)
(x, y) → (x + 1, y)=translation
(x, y) → (–x, –y)=reflection
(x, y) → (2x, y)=scaling->can't be congruent
3)
(x, y) → (0.5x, 0.5y)=scaling->can't be congruent
(x, y) → (x, –y)
(x, y) → (x, y + 8)
4)
(x, y) → (x – 4, y)=translation
(x, y) → (x, y + 3)=translation
(x, y) → (3x, 3y)=scaling->can't be congruent
so 1) is the only series of transformations with a congruent solution
F’= 7+2x, plz mark my answer~
