Answer:

84

Step-by-step explanation:

Let x = the test

(x + x + ( x - 6))/3=82

((3x - 6)/3) • 3= 82 • 3

3x - 6 + 6 = 246 + 6

<u>3x</u> = <u>252</u>

3        3

x = 84

An angle measures 138° less than the measure of its supplementary angle. What is the
iren2701 [21]

The measure of each angle is 159° and 21°.

<h3>What are supplementary angles?</h3>
  • When two straight lines or rays intersect at a single endpoint, an angle is created.
  • The vertex of an angle is the location where two points come together.
  • The Latin word "angulus," which means "corner," is where the word "angle" originates.
  • Two angles are considered to be supplementary if their sums total 180 degrees.
  • For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.

So, supplementary angles = 180

Then,

  • 2x + 138 = 180
  • 2x = 180 - 138
  • 2x = 42
  • x = 21
  • 21 + 138 = 159

Therefore, the measure of each angle is 159° and 21°.

Find the slope of line that contains the points (-4,-13) and (8,5).
gtnhenbr [62]
We can use y2-y1/x2-x1 to find the slope. Therefore, we have:
-5-(-13)/8-(-4). That gives us -5+13/8+4, or 8/12 = 2/3.
Hope this helps!
