Find the value of a°

Mathematics

Answer:

If two vectors are parallel, applying the same side interior angles theorem:

=> 80 + a + 59 = 180

=> a = 180 - 80 - 59 = 41 deg

Hope this helps!

Or you could apply alternate angle theorem

Alternate angles make a "z" shape. Alternate angles are equal

So now that we know the third side of the triangle is equal to 59, we do 180=a+59+80

Move fifty nine and eighty to the other side as negative numbers

a=180-59-80

So, a is equal, to 41 :))

Consider the line y=4x-4.
erica [24]

9514 1404 393

Answer:

  • parallel: y = 4x -6
  • perpendicular: y = -1/4x +27/4

Step-by-step explanation:

If we want the new line to be written in slope-intercept form, we need to find the new value of the y-intercept. The equation of the line is ...

  y = mx +b . . . . . . . for slope m and y-intercept b

Solving for b gives ...

  b = y -mx . . . . . . . subtract mx from both sides.

The values of x and y come from the point we want the line to pass through. The value of m will be the same for the parallel line as for the given line: 4. For the perpendicular line, it will be the opposite reciprocal of this: -1/4.

<u>Parallel line</u>

  b = 6 -4(3) = 6 -12 = -6

  y = 4x -6

Perpendicular line

  b = 6 -(-1/4)(3) = 6 +3/4 = 27/4

  y = -1/4x +27/4

Which is the graph of the system of inequalities
Leni [432]

Answer:

A

Step-by-step explanation:

Try testing each graph by picking a point on the shaded region or none shaded region.

-1/5 and 6= y-intercept

4/5 and 2= slope

You may notice that it is in y-intercept form. So to find where the shaded region goes, test a coordinate and apply it to the equation, if the answer is false, than half of the line is not where the shaded region goes.
