Answer: Your answer is B
Step-by-step explanation:
Pls mark me brainiest
Explanation 1:
Jennifer knows that at least one of Franklin's measures of the angles of the triangle is incorrect because the sum of the inner angles of a triangle is equal to 180°.
When you add the shown measures you get:
- 37° + 97° + 134° = 268° ≠ 180°, which makes this an impossible triangle.
Explanation 2:
Jennifer also can know that either the measure 97° or 134° (or even both) is incorrect.
This is so because the addition of those two measures is
Since 231° > 180° those measures cannot be correct because the sum of two angles of an triangle has to be less than 180°, given that when they are summed to the other angle the sum has to be 180°.

Answer:
n = -14
Step-by-step explanation:
-3(n+9)=15
Distribute -3 to (n+9):
-3n - 27 = 15
Add 27 to both sides:
-3n = 42
Divide both sides by -3:
n = -14
