Answer:

The value of x is 11.

Step-by-step explanation:

Given :

Here we have given that the angles of a triangle are :

  • [tex]\pink\star[/tex] 62⁰
  • [tex]\pink\star[/tex] 69⁰
  • [tex]\pink\star[/tex] 4x + 5

[tex]\begin{gathered}\end{gathered}[/tex]

To Find :

  • [tex]\pink\star[/tex] We need to find the value of x.

[tex]\begin{gathered}\end{gathered}[/tex]

As we know that :

  • [tex]\pink\star[/tex] The sum of the angles of a triangle is always 180 degrees.

[tex]\begin{gathered}\end{gathered}[/tex]

Solution :

Now, according to the question :

[tex]\begin{gathered}\quad\longrightarrow{\sf{Sum \: of \: all \: angles = {180}^{0}}} \\\\\quad\longrightarrow{\sf{{62} + {69} + 4x + 5 = {180}}}\\\\\quad\longrightarrow{\sf{{131} + 4x + 5 = {180}}}\\\\\quad\longrightarrow{\sf{4x + 5 = {180} - {131}}}\\\\\quad\longrightarrow{\sf{4x + 5 = 49}}\\\\\quad\longrightarrow{\sf{4x = 49 - 5}}\\\\\quad\longrightarrow{\sf{4x = 44}}\\\\\quad\longrightarrow{\sf{x = \frac{44}{4}}}\\\\\quad\longrightarrow{\sf{x = 11}} \\ \\ \quad{\star{\underline{\boxed{\sf{\purple{x = 11}}}}}}\end{gathered}[/tex]

Hence, the value of x is 11.
