Find the measure of the angle indicated.​

Mathematics
1 answer:
MakcuM [25]3 years ago

The answer is A. Angles of a triangle will always add up to 180. If you add up 70+67+57 you are left with 194, which is 14 more than 180. Because we need to be at 180, we can assume that x is a negative number. If we say x is negative 7 we are able to takeaway 7 from 67 and 57. After this, we see that the sum of our angles is 50+60+70=180. Therefore, x=-7 in this situation and angle A is equal to 60. The answer is A.

Need help with this please!!!
BARSIC [14]
I don't like dividing polynomials so I'm going to set x=1 and try them out.

(1-2-14+3)/4 = -3

Of the choices, only D gives -3 when x=1

~~~~~~~~~~~~~~~~~~~~~~

That's as much test-taking as math.  If we were to divide


             x^2 - 5x + 1
          -------------------------------
x + 3 |   x^3 - 2x^2 - 14x + 3
             x^3 + 3x^2
                      -5x^2 - 14x
                       5x^2 + 15x
                                      x + 3 
                                      x + 3

More work, still choice D

Which equation represents the line that passes through the point (1,5) with a slope of-2
svlad2 [7]

Answer:

The equation of the line would be y = -2x + 7

Step-by-step explanation:

In order to solve this, use the point and the slope in point-slope form. Then solve for y.

y - y1 = m(x - x1)

y - 5 = -2(x - 1)

y - 5 = -2x + 2

y = -2x + 7

Systems by graphing
Levart [38]

Answer:

A system of linear equations contains two or more equations to solve a problem.  We graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
