Its the first one for all three of the questions
Let the common difference between 2 consecutive pizzas be x.
The pizza is cut into slices of
90°, 90°-x, 90°-x-x, 90°-x-x-x, 90°-x-x-x-x, 90°-x-x-x-x-x,
that is
90°, 90°-x, 90°-2x, 90°-3x, 90°-4x, 90°-5x
the sum of these angles is 360°, so:
90°+90°-x+90°-2x+90°-3x+90°-4x+90°-5x=360°
90°*6-15x=360°
540°-360°=15x
180°=15x
x=12°
The degree measure of the fifth slice is 90°-4x=90°-4*12=90°-48=42°
Answer: 42°
