Answer:
5.87
Step-by-step explanation:
The tangent relation tells you ...
Tan = Opposite/Adjacent
tan(50°) = 7/BC
BC = 7/tan(50°)
BC ≈ 5.87
Since the dilatation is centred at the origin then multiply each of the coordinates of the vertices by the scale factor.
(- 4, 2 ) → (- 4, 2 ) → (- 2, 1 )
Similarly
(- 2, 8 ) → (- 1, 4 )
(2, 4 ) → (1, 2 )
Answer:
2
Step-by-step explanation:
5x+3x=14+2
8x=16
x=2
...
Step-by-step explanation:
f(x) = |x-7| + 3
when x is equal to 4, then
f(4) = |4-7| + 3
=-3+3
=0
