What is the first step to solve for x?

The first step to solving for ​x​ is going to be getting ​x​ alone on one side of the equation and everything else on the other side. Remember the algebraic golden rule: What you do to one side of the equation, you must do to the other side. That’s how the equation stays equal!

How do I calculate X?

Isolate “x” on one side of the algebraic equation by subtracting the sum that appears on the same side of the equation as the “x.” For example, in the equation “x + 5 = 12”, rewrite the equation as “x = 12 – 5” and solve for “x.” The solution is “x = 7.”

How do you find the X in a triangle?

Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X.

How do you solve X in a triangle?

Solving for X in a Right Triangle. Add 90 degrees for the right angle to the degree measurement of the other marked angle. This measurement will be found inside the triangle at the angle that is not denoted by the X variable. Subtract the sum of the two angles from 180 degrees.

How do you figure out the side of a triangle?

To find the sides of the triangle, you need to use the Law of Sines. A scientific calculator with trigonometric functions will help you to find the sine of each of the angles. According to the Law of Sines, the ratio of the sines of each angle divided by the length of the opposite side are all equal. This helps you to find the sides of the triangle.

How do you find the missing measure of a triangle?

The key to finding the missing angle measure of a triangle is to remember that the sum of the interior angles of any triangle is always 180°. If you know 2 angles then you can subtract their sum from 180° to find the measure of the 3 rd angle.
