Question

Can someone help me with this?

Answer 1

so how you think that will get the distance from point S to point T ?

how many you need adding to 7,5 for get 16,3 ?

how you find the distance from point R to point S ?

so step by step - if you see from point R till zero there are 8 units - yes ?
and from zero till point S there are 7,5 units

so how you get the distance now from R to S ?

hope helped understandably easy
