Question

Identify the range of values for x.
3x + 3
80⁰
x + 17
100⁰

Answer 1

Answer:
`-1 < x < 7`

Explanation:

Because 80 degrees is smaller than 180 degrees, but there are 2 pairs of congruent sides that form the labeled angles,

`3x+3 < x+17\\\\2x < 14\\\\x < 7`

However, the side lengths must be positive, so x > -1 (because of 3x+3).

So, the range is
`-1 < x < 7`
