Given:
The equation is
To find:
The reason for each statement.
Solution:
We have,
Using distributive property, we get
On combine like terms, we get
Using addition property of equality, add 2x on both sides.
Using subtraction property of equality, subtract 7 from both sides.
Using division property of equality, divide both sides by 20.
Therefore, the required reasons are:
2. Distributive property
3. Combining like terms
4. Addition property of equality
5. Subtraction property of equality

Consider the right triangle between the plank and the ground
the angle can be found using tangent ratio
tanx° =
where adjacent = 18 and opposite = 10
tanx° =
x = (
) = 29.0546 ≈ 29°
