Answer:

1. complementary

2. neither

3. supplementary

4. complementary (x = 6)

10x + 30 = 90 x + 3 = 9 x = 6

5. supplementary (x = 20)

4x + 40 + 3x = 180 7x = 140 x = 20

6. x = 50.5

2x + 79 = 180 2x = 101 x = 50.5

Step-by-step explanation:

When the measurement of the angles adds up to 90 degrees, the angles are complementary. When the sum of the angles is 180 degrees, then they are supplementary.

Answer:

supplementary angles - two angles are supplementary when they add up to 180 degrees (a straight line)

complementary angles - two angles are complementary when they add up to 90 degrees (a right angle)

hopefully this helps! :)

Look at the figures. How can you prove these triangles are congruent?

Answer:

A. $\Delta ABC\cong \Delta DEF$ by the SAS postulate.

Step-by-step explanation:

We have been two triangles. We are asked to determine the theorem by which both triangles could be proven congruent.

We can see that side DF of triangle DEF is equal to side AC of triangle ABC.

We can also see that side BC of triangle ABC is equal to side EF of triangle DEF.

The including angle between sides AC and BC of triangle ABC is equal to the including angle between sides DF and EF of triangle DEF.

Since both triangles have two sides and their included angles equal, therefore, triangle ABC is congruent to triangle DEF by SAS (Side-Angle-Side) congruence and option A is the correct choice.
