Toby goes on holiday to geneva, switzerland.
in geneva, toby sees a watch costing 193.75 chf (swiss francs).
in manchester, an identical watch costs £143
given that £1 = 1.55 chf

a) in which city is the watch cheaper?

b) by how much is it cheaper (in £)?

If

Then:

Now we can make the comparisons:

a) In Geneva the watch costs and in Manchester it costs .

According to this:

b) If we want to know by how much is cheaper, we have to substract from the expensive price the value of the cheaper price:

Therefore:

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

what is the answer?
