If we are talking about degrees they should equal 180
Answer:
BC = 30.73
Here,

so first solve for QD




Now! <u>using Pythagoras theorem,</u>
- BC = 30.73 ( rounded to nearest hundredth )
It's a linear function.
Domain of a linear function is the set of all real numbers.
If the slope of linear function is different than 0, then range is the set of all real numbers.
We have f(s) = 7s + 15. The slope = 7 ≠ 0. Therefore:
Answer:
