**Answer:**

the third one and the last one is correct

**Step-by-step explanation:**

we already know the second one is wrong because of it's set up.

just replace the points (-1,7) into each equation. if it doesn't work then move on to the next one. if it does work, then use that same equation except this time to the coordinates (2,4)

**Answer:**

x=1/4

**Step-by-step explanation:**

1/4+3/4=1 whole

**Answer:**

3. m∠A < 80°

**Step-by-step explanation:**

The exterior angle NGS, marked as 80°, has a measure that is the sum of the measures of the remote interior angles: GAN, GNA.

If we assume that angle measures cannot be zero, then we must have ...

m∠A +m∠N = 80°

m∠A = 80° -m∠N

Since m∠N > 0, the measure of **angle A must be less than 80°**.

This conclusion **matches choice 3**.
