Let's begin by listing out the information given to us:
A cubic function has the general form of:

The function has real coefficients
Its zeros are 0, 1 & -4
For number 11 the third angle would be equal X as the second angle is, since the two sides next to the those angles are congruent. Then you would have to set an equation saying that 2x + 38= 180 and then you can just solve for X
Answer:

Step-by-step explanation:
-64 would be the whole number.
.875 would be 875/1000 as a fraction.
Put them together:
