- Starting point of arrow is -6.
- The arrow is travelling to wards left.
- I.e the arrow is decreasing and x is decreasing.
Hence the solution is
- x<=-6
Similar shapes may or may not be congruent.
The value of x is (a) 9.0
The corresponding sides are:
- AB and DE
- BC and EF
- AC and DF
The side lengths are:
Because the shapes are congruent, and AC corresponds to DF.
This means that:
So, we have:
Collect like terms
Divide both sides by 5
<em>Hence, the correct option is (a) 9.0</em>
