Question

What is the range of possible values for x?

Answer 1

it's written (x-6)° on the picture?

Answer 2

yes

Answer 3

note \(y=x-6\). the angle \(y\) is smaller than 28°, because

Answer 4

why does y equal x-6?

Answer 5

it's just a name.

Answer 6

Notation: * y=x-6.

Answer 7

oh okay, but how do you find out the range?

Answer 8

y≤28 is the same as x-6 ≤ 28 which is the same as x≤34. I would choose that as upper bound.
for the lower bound, idk

Answer 9

well, the angle \(y\) is not negative. So it's correct to write \(y≥0 \iff x\ge 6\) . I would say that..

Answer 10

im so confused right now

Answer 11

so it would be 0<x<6 ?

Answer 12

no, upper boud: 34, lower bound : 6.
so, \(6<x<34\).

Answer 13

why not 7 instead of 6?

Answer 14

its ok, thanks for your help!!
