How do i solve for x within a triangle?

Since there are 180 degrees in a triangle and a right angle (signified with the diamond at the top) is 90 degrees, the remaining angles are 180-90=90 degrees. Therefore, 2x+1+5x+5=90=7x+6. Subtracting 6 from both sides, we get 7x=84. Next, we divide both sides by 7 to get x=12

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.

so the perpendicular line goes through the given pointyou would get a perpendicular line at some random location

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
