<h2>Answer:</h2>

option: b is the correct answer.

b. The adjacent angles formed by two intersecting lines are supplementary.

<h2>Step-by-step explanation:</h2>

Clearly from the figure that is given to us we could see that we are given measures of the adjacent angles (i.e. the angle that have a common vertex and a common side)

Hence, also by the given measures we have:

  • 135°+45°=180°.
  • 160°+20°=180°
  • 130°+50°=180°

This means that the adjacent angles formed by two intersecting lines are supplementary ( since the sum of the two angles is 180°)

Hence, option:b is correct.

Answer: b. The adjacent angles formed by two intersecting lines are supplementary.


Step-by-step explanation:

In the given picture , we can see that there are intersecting lines with adjacent angles which have shown.

If we add the adjacent angles for each pair of intersecting lines we get,

135^{\circ}+45^{\circ}=180^{\circ}

130^{\circ}+50^{\circ}=180^{\circ}

160^{\circ}+20^{\circ}=180^{\circ}

Therefore,b is the right option "The adjacent angles formed by two intersecting lines are supplementary."

  • Two Angles are supplementary when their sum is 180 degrees.
  • Two Angles are complementary when their sum is 90 degrees.
  • Vertical angles are always equal.

How do you write 16x-3y=3 in slope intercept form
serg [7]
Y=16/3 x -1

First, you minus both sides by 16x. This will get you -3y = 3 - 16x

Then, you divide both sides by -3. Hence on the right hand side you will get 3 - 16x over -3, which can be split into (-16x/-3) + (3/-3). By simplifying this you can get 16/3 x - 1.
