Answer:

Angle A=116\°

Step-by-step explanation:

Given:

Three angles of a triangle ABC.

A(9x+17)\\B(3x-4)\\C(6x-31)

Angle sum of a triangle is always = 180°

∴ A+B+C=180\°

Plugging in values of A,B \ and\ C

(9x+17)+(3x-4)+(6x-31)=180

Combining like terms.

9x+3x+6x+17-4-31=180

18x-18=180

Adding 18 both sides.

18x-18+18=180+18

18x=198

Dividing both sides by 18.

\frac{18x}{18}=\frac{198}{18}

∴ x=11

Angle A=9x+17

Plugging in value of x

Angle A=9(11)+17

Angle A=99+17

Angle A=116\°

KengaRu [80]

Answer:

Independent: Amount of hours she works

Dependent: Amount of money she makes

Step-by-step explanation:

The independent variable is the part of the equation that changes. In this case the only thing that changes is how long she works, the amount of money she charges and what she is doing does not change.

The dependent variable is what you measure in the equation. In this case, the amount of money she makes <em>depends</em><em> </em><em>on</em> the amount of time she works.
