Answer:

37°

Step-by-step explanation:

sum of exterior angles of a polygon is 360°

so, 41+(x+13)+(2x-14)+(3x-22)+(x-3)+38+(x+11)=360

8x+64=360, subtract 64 from both sides

8x=296

x=37°

Find a polynomial function p of lowest degree, having rational coefficients, with the given zero. 5i

weqwewe [10]

If we have one zero of +5i, we also have to have its conjugate which is -5i. Therefore, the factors that we will FOIL to get that polynomial are (x+5i)(x-5i). That distribution results in $x^{2} -25 i^{2}$ . I'm sure by now you know that i squared is equal to -1, so -25(-1) = 25. So our polynomial is $x^{2} +25=y$
