Step-by-step explanation:
As per the problem, the given triangle is a right triangle. This is signified by the box around one of its angles, this box states that the angle it is surrounding is a right angle.
Since it is a right triangle, one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that; (), where (
) and (
) are the legs of the right triangle, or the sides adjacent to the right angle. (
) is the hypotenuse or the side opposite the right angle.
Substitute in the given values and solve, note that () represents the unknown leg (side).

The correct question as understood from the statement is:
Determine which equations have the same solution set as 2/3 – x + 1/6 = 6x by recognizing properties, rather than solving. Check all that apply.
a) 4 - 6x + 1 = 36x
b) 5/6 - x = 6x
c) 4 - x + 1 = 6x
d) 5/6 + x = 6x
e) 5 = 30x
f) 5 = 42x
Answer:
Options: a, b and f
Step-by-step explanation:
The given equation is:
Adding x to both sides, we get:
Option a) 4 - 6x + 1 = 36x
Moving 6x to the right hand side of the equation and simplifying the answer, would give us 5 = 42x, which is the same as the second last equation in above simplification. Thus this equation has the same roots.
Option b) 5/6 - x = 6x
Moving x to other side will give us the same equation as we got in 3rd last step of the above simplification. Thus this equation has the same roots.
Option c) 4 - x + 1 = 6x
Moving x to other side, and simplifying the result gives us an equation which does not match with the equations in above simplifications. So, this equation does not have the same root.
Option d) 5/6 + x = 6x
Moving x to other side, and simplifying the result gives us an equation which does not match with the equations in above simplifications. So, this equation does not have the same root.
Option e) 5 = 30x
This does not match with the second last step of the above simplification. So, this equation does not have the same root.
Option f) 5 = 42x
This equation matches with the second last step of the above simplification. Thus this equation has the same roots.
