Given:
A figure of a right angle triangle.
To find:
The value of x°.
Solution:
The given triangle is a right angle triangle. So, the measure of one angle is 90 degrees.
The measure of other two angles are 3x° and 7x°.
According to the angle sum property of a triangle, the sum of all three interior angles of a triangle is 180 degrees.
Using the angle sum property of the triangle, we get
Divide both sides by 10.
Therefore, the value of x° is equal to 10°.

N is a placeholder for a number. In this case, it is 4
We will replace every copy of 'n' with '4' and then simplify
So n+8 turns into 4+8 which simplifies to 12
Is 12 less than or equal to 13? Yes it is. Specifically it is less than 13. So n = 4 is part of the solution set.
Here is how you'd write it all out using algebra
The last inequality is true so the first inequality is true when n = 4. This is another way to see that n = 4 is a solution.
