Answer:

solution,

x+85+24=180 (being sum of angle of triangle)

x+109=180

x=180-109

x=71

therefore, the third angle is 71

Answer just below :-

Step-by-step explanation:

Let the third angle be x

Then;

24°+85°+x = 180 ( sum of interior angles of a triangle is 180°)

or; 109°+x = 180°

or; x = 180°-109°

:x=71°

Therefore the measure of third angle is 71°

Vlad1618 [11]

Answer:

16

Step-by-step explanation:

7+16+11+12+10= 56

In order to find the 6th number, you must multiply 12 and 6.

12*6= 72

72-56= 16

Double check your work:

7+16+11+12+10+16= 72

72/6= 12

Geet sells televisions. He earns a fixed amount for each television and an additional $ 30 if the buyer gets an extended warrant
pashok25 [27]

Answer:

The fixed amount Geet earns for each television is <u>$60</u>.

Step-by-step explanation:

Given:

Geet sells televisions. He earns a fixed amount for each television and an additional $ 30 if the buyer gets an extended warranty.

If Geet sells 17 televisions with extended​ warranties, he earns $ 1,530.

Now, to find the fixed amount Geet earns for each television.

Let the cost of fixed amount be x.

Number of television = 17.

He earns total = $1,530.

He earns additional amount = $30.

Now, to get the fixed amount we put an equation:

17(x+30)=1530

17x+510=1530

<em>Subtracting both sides by 510 we get:</em>

17x=1020

<em>Dividing both sides by 17 we get:</em>

x=60.

Therefore, the fixed amount Geet earns for each television is $60.

What are the roots of the polynomial equation x^3-6x=3x^2-8? Use a graphing calculator and a system of equations.
Tanzania [10]
Given the polynomial equation x^3 -6x = 3x^2 – 8. Which can be simplified into (x^3) -3(x^2) -6x +8 = 0. The roots of the given equation are x = -2, x = 1 and x = 4. The order  of equation also represents the number of roots of the equation given. Since the highest exponent is 3, there also 3 roots. So the answer is D. 2 –2, 1, 4

Answer:

  y = -1/6x +2

Step-by-step explanation:

The black vertical line in the middle of the graph is the y-axis. The blue line crosses it a the point marked 2. This is known as the y-intercept.

The slope of the line is the ratio of "rise" (vertical change) to "run" (horizontal change).

There is a marked point on the line at the y-intercept, where x=0 and y=2. There is another marked point to the right of that, where x=6 and y=1.

The vertical change between those two points is 1 -2 = -1.

The horizontal change between those two points is 6 -0 = 6

The slope is then -1/6.

__

The slope-intercept form of the equation of a line is often written as ...

   y = mx + b

where "m" is the slope (-1/6), and "b" is the y-intercept.

Using the values we found above, the equation of the line is ...

  y = -1/6x +2
