Mathematics
1 answer:
Rudik [331]3 years ago
6 0

Step 1: Add the two equations.

Step 2: Solve for x.

Step 3: To find the y-value, substitute in 3 for x in one of the equations.

Step 4: Solve for y.

Step 5: Identify the solution as an ordered pair.

What if adding or subtracting does not eliminate a variable? Example. 3x – y = 8. x + 2y = 5.

"An angle that forms a linear pair with one of the interior angle the triangle" is the best definition of an exterior angle of a triangle.

<u>Option: C</u>

<u>Explanation:</u>

When to the sum of the inward angles opposite outer angle of a triangle the sum of the inward angles opposite is equivalent thus understood as exterior angle of a triangle.

The Triangle outer angle theorem for more about is if at each vertex the equivalent angle is drawn, the outer angles always add up to 360°. In reality, this is valid for any convex polygon, not just triangles.

In the most easiest pattern , since any angle of triangle equivalent is 60′, the outer angle would be 120′. Therefore all exterior angles sum is:

                     120 + 120 + 120 = 360°.
