A path is made of red tiles and blue tiles. 1/5of the tiles are red.
a) Write down the ratio of red tiles to blue tiles in its simplest form.

There is a total of 85 tiles.
b) Work out the number of blue tiles.
(2)
Total marks: 3

17 red , 68 blue

Step-by-step explanation:

85 divided by 5=17

1/5 of 85=17

17x4=68

4/5 of 85=68

step-by-step explanation:

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.
