the values of y varies directly with x and y=8 when x=2. find y when x=10.

y=40

Step-by-step explanation:

It is given that y directly varies with x.

Hence we can write the relation between x and y as:

where k is an arbitrary constant

It is also given y=8 when x=2 then k=

So the relation is

Therefore when x=10,

r and t.

both are 64 degrees.
