Front

How do you set up an equation to find x in a linear equation?

Back

Identify the terms involving x on both sides and isolate x by performing inverse operations.

Front

What is the solution to the equation 42 + 8x = 2 + 12x?

Back

x = 11.

Front

What is the equation to find a missing angle if two angles sum to 180 degrees?

Back

x + (sum of known angles) = 180.

Front

What is the measure of angle 2 if it is given as 50 degrees?

Back

Angle 2 measures 50 degrees.

Front

What is an Equilateral Triangle?

Front

What is an Obtuse Triangle?

Back

A triangle that has one angle greater than 90 degrees.

Front

What is a Scalene Triangle?

Back

A triangle with all sides of different lengths and all angles of different measures.

Front

How do you solve for x in the equation 42 + 8x = 2 + 12x?

Back

Rearrange the equation to isolate x: 42 - 2 = 12x - 8x.

Front

What is the sum of angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.
