The coordinates are (-1 , 3).
this can be shown by simplifying the equation into perfect squares.
Answer:
3^-2=1/9
3^0=1
3^1=3
3^2=9
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, that is
∠ 1 + ∠ 2 + ∠ 3 = 180°
Given ∠ 1 + ∠ 2 = 134°, then
134° + ∠ 3 = 180° ( subtract 134° from 180° )
∠ 3 = 46° → D
