Answer 2

do you see "small dashes" on chords FN and NU ?

Answer 3

the arc means a curve line on top of the letters

Answer 4

FN and NU have a curve line on them

Answer 5

yes what does that tell you ?

Answer 6

those small dashes tells us that they have same lengths :


FN = NU

Answer 7

set the given expressions equal to each other and solve x

Answer 8

so 5x - 10 = 3x + 30
5x - 3x = 30 + 10
2x = 40
x = 20
