Angle a and angle b are supplementary angles. what must be true about the angles? a. the sum of the angles is 90 degree b. the sum of the angles is 180 degree c. the angles were formed by two intersecting lines and are on opposite sides. d. the angles share a common side and vertex.

Solution:

As per the problem we have

Angle A and angle B are supplementary angles.

As we know that , two angles are supplementary angles if their sum is 180.

So when these two angles will be together on a plane will make a straight line.

Hence , when Angle A and angle B are supplementary angles.

Then

The sum of the angles is 180 degree.

the distance between point a and point b is 6 units

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
