You missed the value of the slope and that information is needed.

Any way, I can show you how to calculate the answer given a generic value of the slope.

Assuming that the slope values m, you can use the formula:

**m = rise / run = change in y / change in x**

**=> m = (n - 5) / (16 - 10)**

**=> n - 5 = m (16 - 10) **

**=> n - 5 = 6m**

**=> n = 6m + 5**

Now I am going to calculate the value of n for several values of the slope (m):

m n = 6m + 5 answer

1/2 n = 6(0.5) + 5 = 8 the first option

-1/2 n = 6(-0.5) + 5 = 2 the second option

5/6 n = 6(5/6) + 5 = 10 the third option

11/6 n=6(11/6) + 5 = 16 the fourth option

1/6 n = 6(1/6) + 5 = 6 the fifth option

Now you have the procedure and the answer for several values of the slope, so you do not have problems to answer this question.

**Answer:**

21.6 degrees

**Step-by-step explanation:**

the sum of angles in a triangle is 180 degrees

71 + x + (4x-11) = 180

open the brackets

71 + x +4x - 1 = 180

71 + 1 + x + 4x =180

72 + 5x =180

5x = 180 -72

5x = 108

x = 108/5 = 21.6

**Answer:**

I think it's AB

**Step-by-step explanation:**

Since its the opposite of AD

3 * (-4) When you multiply a positive by a negative your answer will always be negative. 3 x 4 is 12.

**-12**
