Answer:
The 3rd option
Step-by-step explanation:
To prove that 2 triangles are similar, we need to prove that 2 pairs of their angle measurements are congruent.
This is because all triangles have 180 degrees, so if 2 pairs are congruent, the remaining angles will also be congruent
We know that m<D=m<E
We also know that m<DCA=m<ECB because they are vertical angles.
Vertical angles are always congruent.
Therefore, the triangles are similar.
The correct similarity statement would be 1, since <D corresponds with <E.
Now let's look at the 3rd Statement. To prove that two lines are similar, we would have to prove that their alternate interior angles are congruent.
A pair of alternate interior angles would be <D and B or or <E and <A
There is no way to prove this, since we do not know any of the angle or that measurements or if the triangles are isosceles triangles.
Hence, the correct choice would be 1 only.
Calculate the width
14:2=7
having given that the lenght is 14 in her slices too it means that she cuts it only in one direction so the width is
7:9=0.77777 (seven in period)
so she is pretty inacurate
Answer:

Step-by-step explanation:
Since, a coin is thrown with velocity "u"=0m/s and time "t"=1.2s,it gains an acceleration due to gravity, then using the formula,
;
Since u=0 and g=9.81, therefore,




the answer is B.......................
