As an estimation we are told £3 is €4. convert £12.30 to euros. give your answer rounded to 2 dp.

€16.40

Step-by-step explanation:

First, we need to divide £12.30 by 3 to find out how many groups of 3 there is:

12.3 ÷ 3 = 4.1

Now we can multiply this by 4 to find the euro equivalent:

4.1 * 4 = 16.4

So £12.30 is €16.40

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

12*c
