There are two angles that form a straight line together.
Angle D holds 7Y - 18 degrees, and angle F holds 2Y.
What is the actual amount of degrees each angle holds?

Answer: F=44 and D=136

Step-by-step explanation:

If the two angles form a straight line, they are supplementary angles, so they sum 180 degrees. This is:

D + F = 180

[tex]7Y - 18 + 2Y=180\\9Y = 198\\Y=22\\\\D = 7(22)-18\\D=136\\\\F=2(22)\\F=44[/tex]
