Answer:
A'(-1,1), B'(-5,1), C'(-3,3)
Step-by-step explanation:
Reflection across the y-axis replaces the x-coordinate with its opposite.
h=0.4
6.1h=2.44
h=2.44/6.1
=60 the second option.
Given the trigonometric ratio, we can find the value of the angle by simply finding the inverse of the given ratio.
If for example Cos ∅= a, then ∅=Cos⁻¹a
If Cos (x)= 0.5, then x= Cos⁻¹ 0.5
Cos⁻1 0.5=60°
The angle whose sine is 0.5 is ∅=60°
