Math Problem Statement

what is the value of x

Solution

The image shows a geometry problem where two angles, 2x2x and 3x3x, are formed by two intersecting lines, and they add up to a right angle.

In a right angle, the sum of the angles is 9090^\circ. Therefore, the equation to solve for xx is:

2x+3x=902x + 3x = 90^\circ

Simplify and solve for xx:

5x=905x = 90^\circ

x=905=18x = \frac{90^\circ}{5} = 18^\circ

Thus, the value of xx is 1818^\circ.

Related Questions:

  1. How would the value of xx change if the angles were complementary instead of a right angle?
  2. What is the measure of the angles 2x2x and 3x3x when x=18x = 18^\circ?
  3. How would you solve this problem if the sum of the angles was 180180^\circ instead of 9090^\circ?
  4. Can this problem be solved using trigonometric identities?
  5. How does understanding this problem help in solving other types of geometric problems?

Tip:

When dealing with angles formed by intersecting lines, always check if they add up to specific angle sums like 9090^\circ, 180180^\circ, or 360360^\circ.
