Can someone help me which one is the shade of the angle

Please check answer for explanations

Step-by-step explanation:

Here, we want to shade the angle

From the measure given, we have the angle as located on the triangle EFD

So, we locate the triangle EFD

afterwards, we look at the angle given again and the letter in the middle

The letter in the middle is F from EFD

so this means that the particular angle we want to locate is on the angle F , which we can then proceed to shade

simply put, shade the measure of angle F in the triangle EFD

a.)the line for function b is steeper
