25 because Becky read 45 and Jason read 20
45-20 = 25
1/5 is .2
.1^2 is .01
.02 is .02
So the furthest left would be the smallest number, which in this case is 0.1^2
The answer is 1:2. all you have to do is add the dots for example 4/5 would be 4:5
Answer:

Step-by-step explanation:
We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is
.
Because all the angles of a triangle sum to
, we have that
.
We combine like terms on the left side to get
.
We subtract
on both sides to get
.
So,
and we're done!
