Help me please I can’t figure out how to do these

48 degrees

Step-by-step explanation:

Since UV is tangent to the circle, this means that it is perpendicular to the diameter UW. This means that angle U is 90 degrees, and that angle W is 90-42=48 degrees. Hope this helps!

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
