Answer:

17

Step-by-step explanation:

The inner angle is 90, and the other is 44, which added together are 134. Because a straight line is 180 degrees, 3n-5 must equal 46. Thus, 3*17-5=51

Answer:

n = 17

Step-by-step explanation:

All angles on a straight line should add up to 180 so we can put this question into an equation:

44 + 90 + (3n - 5) = 180

44 + 90 = 134

134 + 3n - 5 = 180

134 - 5 + 3n = 180

129 + 3n = 180

Subtract 129 from both sides:

129 + 3n - 129 = 180 - 129

3n = 51

Divide both sides by 3:

n = 17

Hope this helps!
