Answer:

Blank 1 :- 2x + (5x - 20) + (x + 10) = 180°

Blank 2 :- x = 23.75

Step-by-step Step-by-step explanation:

As we know that sum of the interior angles of the triangle is equal to 180°, To solve for x, we can add all the three angles

The Equation becomes,
\bf 2x + (5x - 20) + (x + 10) = 180\degree (we can use this equation to solve for x)

Solving for x:-


\sf 2x + (5x - 20) + (x + 10) = 180


\sf 2x + 5x - 20 + x + 10 = 180


\sf 7x - 20 + x + 10 = 180


\sf 8x - 10 = 180

Add 10 to both sides,


\sf 8x = 180 + 10


\sf 8x = 190

Now, divide both sides by 8,


\bf x = 23.75

Hence,

  • Blank 1 :- 2x + (5x - 20) + (x + 10) = 180°
  • Blank 2 :- x = 23.75

The equation we used to solve for x is 8x - 10 = 180, and the value of x is 23.75 (rounded to two decimal places).

To solve for x in triangle GHI, we can use the fact that the sum of the angles in a triangle is 180 degrees.

First, let's set up the equation:

Angle G + Angle H + Angle I = 180

Substituting the given values, we have:

(5x - 20) + (2x) + (x + 10) = 180

Simplifying the equation:

8x - 10 = 180

Now, let's solve for x:

8x = 190

x = 190/8

x = 23.75 (rounded to two decimal places)
