Answer:

60⁰

Step-by-step explanation:

A triangle has three angles.

The sum of its angles = 180⁰

[ By angle sum property ]

Let the unknown angle be 'x'

Then,

30⁰ + 90⁰ + x = 180⁰

120⁰ + x = 180⁰

x = 180⁰ - 120⁰

x = 60⁰

Therefore, the unknown angle will be equal to 60⁰

60° because 90°+ 30°= 120°and 180°-120°=60°

Is (x + 5) a factor of f(x) = x^3 – 4x^2 + 3x + 7? Use either the remainder theorem or the factor theorem to explain your reason

stich3 [128]

ANSWER

Not a factor

EXPLANATION

The given polynomial has equation:

$f(x) = {x}^{3} - 4 {x}^{2} + 3x + 7$

According to the remainder theorem, if (x+5) is a remainder, then f(-5)=0.

Let us substitute x=-5 into the function and evaluate to see if it will simplify to zero.

$f( - 5) = {( - 5)}^{3} - 4 {( - 5)}^{2} + 3( - 5)+ 7$

$f( - 5) = - 125 - 100 - 15+ 7$

$f( - 5) = - 233$

Since the remainder is not zero, x+5 is not a factor of

$f(x) = {x}^{3} - 4 {x}^{2} + 3x + 7$
