(25x)°=(22×+9)° whas the answer
goldfiish [28.3K]

Answer:

x = 3  

Step-by-step explanation:

(25x)° = (22x + 9)°     Divide each side by 1°

  25x = 22x + 9          Subtract 22x from each side

    3x = 9                       Divide each side by 3

      x = 3

<em>Check: </em>

(25× 3)° = (22×3 + 9)°

      75° = (66 + 9)°

      75° = 75°

<h3>What is Orthocenter?</h3>

The intersection of altitudes traced perpendicularly from a triangle's vertices to its opposite sides is known as an orthocenter. It is the location in a triangle where the three angles of the triangle intersect. An orthocenter's three primary characteristics are as follows:

Triangle: A three-sided polygon with three edges.

A triangle's height is the line that runs between its vertices and perpendicular to the other side. A triangle can therefore have three heights, one from each vertices.

Vertex - A vertex is the intersection of two or more lines.
