Find the measure of the indicated angle to the nearest degree.

azamat

Step-by-step explanation:

Let the measure of required angle be x degree

$\therefore \tan \: x = \frac{45}{28} \\ \\ \therefore \tan \: x = 1.60714286 \\ \\ \therefore \: x = {\tan}^{ - 1} (1.60714286) \\ \\ \therefore \: x = {\tan}^{ - 1} ( \tan \: 58.109 \degree) \\ \\ \huge \red{ \boxed{\therefore \: x = 58\degree}}$

Thus, first option is the correct answer.

Determine the product, h(x), of the linear and quadratic factors.

Airida [17]

Answer:

$h(x)=x^3-17x-4$

Step-by-step explanation:

Given $f(x)=x^2 - 4x -1\ and\ g(x)=x+4\\$

$h(x)=f(x)\times g(x)$

$(x^2-4x-1)(x+4)\ \ \\Distribute\ parenthesis\\=x^2x+x^2\times \:4+\left(-4x\right)x+\left(-4x\right)\times \:4+\left(-1\right)x+\left(-1\right)\times \:4$

Apply minus-plus rules

$+(-a)=-a$

$=x^2x+4x^2-4x(x)-4\times\:4x-1\times\:x-1\times\:4$

$\\Simplify\\=x^3+4x^2-4x^2-16x-x-4\\=x^3-16x-x-4\\=x^3-17x-4$

$h(x)=x^3-17x-4$

5/2x+1/2x=10+7/2x<br><br> PLEASE I NEED HELP ;))))

zlopas [31]

Answer:

The answer is that x = -20.

Step-by-step explanation:

The equation:

5/2x + 1/2x = 10 + 7/2x

6/2x = 10 + 7/2x

-7/2x + 6/2x = 10

-1/2x = 10

-1/2x * -2 = 10 * -2

x = -20

Proof:

5/2*-20 + 1/2*-20 = 10 + 7/2(-20)

-50 + (-10) = 10 + (-70)

-50 - 10 = 10 - 70

-60 = -60
