Question:

Two angles in a triangle equal 120 degrees. What is the measure of the third angle?

A triangle is 180 degrees and there are three types of triangles -- an equilateral triangle which means all three angles equal the same, an isosceles triangle in which two angles are equal, and a scalene triangle in which all three angles have different measurements. Because we already know the sum of two angles, we simply need to subtract the total of those two angles from the 180 degrees. 180 - 120 = 60 degrees. The measure of the third angle is 60 degrees.

Question:

4x + 5 = 8 + 2x

In this problem, we need to determine the value of x. In order to do that, we must shift the components of our problem around to where all the values with an 'x' are on one side. 4x + 5 = 8 + 1x We will keep 4x where it is and bring the + 1x from the right side of the equation to the left. As we shift the + 1x, we need to be mindful of the signs associated with each number. As the 1x is a positive value, it will acquire a negative value as it moves to the opposite side of the equation. Hence becoming 4x + 5 - 1x = 8. Since our primary purpose is to get all the values with an 'x' to one side, we will shift the +5 to the right side of the equation. Again, we need to be mindful of the signs meaning +5 will become a -5 as it moves to the right side becoming: 4x - 1x = 8 - 5 We are able to subtract 4x - 1x because both values have an x. It would not be possible to perform this action if 1x was 1y. 4x - 1x = 3x and 8 - 5 = 3 Now our equation is 3x = 3. We still need to determine the value of x. In order to do so, we must separate 3x. When there is no sign between two numbers, it means that we are multiplying the two values and the opposite of that operation is division. As we take the 3 from 3x to the other side of the equation, we will divide. x = 3/3 x = 1 The value of x = 1.
