angle and angle b are complentary angles. if angle a = (2x-5) and m angle b = (5x+4) then find the measure of angle a
iris [78.8K]

complementary angles = 90

2x-5 + 5x+4 = 90

combine like terms

7x-1 =90

7x = 91

divide by 7

x =13

angle a

2x-5

2*13-5

26-5

21

Angle a: 21

Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in s
Jobisdone [24]

Answer:

f(x)=x^4-9x^2-50x-150

Step-by-step explanation:

Let f(x) be the polynomial function of minimum degree with real coefficients whose zeros are 5, -3, and -1 + 3i be f(x).

By the complex conjugate property of polynomials, -1-3i is also a root of this polynomial.

Therefore the polynomial in factored form is f(x)=(x-5)(x+3)(x-(-1+3i))(x-(-1+3i))

We expand to get:f(x)=(x^2-2x-15)(x^2+2x+10)

We expand further to get:\

f(x)=x^4-9x^2-50x-150
