F(6) = 7(6) - 4
f(6) = 42 - 4
f(6) = 38
Hope this helps!
Can you tell me what you need help because it doesn't says
Subtract the sum of the angles from 180 degrees to get the missing angle. For example if a triangle in a quadrilateral had the angles of 30 and 50 degrees, you would have a third angle equal to 100 degrees (180 - 80 = 100).
594 7/25 converted into decimal is 594.28, 89 37/100 converts to 89.37. Add 594.28 and 89.37 together and we get out final answer of 683.65. Convert that back into fraction form and we get (683 13/20) <--- Final Answer
