It's a half of an equilateral triangle because their angles measure 30° and 60° (an equilateral triangle has 3 angles of 60°)
So x=(2h/√3)/2=h√3=27√3≈15.6
Add the x to both sides and it turns into Y = x + 4. If this isn't what you're looking for, please provide the answer choices.
Answer:
B. (3, –1)
Step-by-step explanation:
Reflection in the line y=-x is described by the transformation ...
(x, y) ⇒ (-y, -x)
Then the point of interest becomes ...
F(1, -3) ⇒ F'(3, -1) . . . . matches choice B
i will use proportions for this.
x 52
------- = --------
2650 100
Cross multiply and u get 1378.
Hope it helps. :)
