Answer:
We know that the sum of the the interior angles of a quadrilateral is 360°.
In the figure, angle H = angle F
angle H+ angle F+ angle E+ angle G =360°

Therefore, <em><u>Angle F = 121°.</u></em>

Step-by-step explanation:
Answer:
b. 5x + 4y = 80
Step-by-step explanation:
Let us assume the remaining balance left be Y
and, the number of songs purchased be X
Given that
Wins a gift card of $20
And, the songs purchased is 16
Now if we take the fraction
= 20 ÷ 16
= 5 ÷ 4
So if we reverse this fraction
So it could be 5x and 4y
And, the amount that would come is
= $20 × 16 ÷ 4
= 80
So, the equation is 5x + 4y = 80
Hence, the correct option is b.
