Chapter SR21, Problem 2P

Solution

Find the value of x.

  $x={109}^o$

Given:

The given triangle.

  

Concept Used:

• The sum of the interior angles of a triangle is $={180}^o$

Calculation:

The given triangle is -

  

As the sum of the interior angles of a triangle is $={180}^o$

  $\begin{array}{c}{37}^o+{34}^o+x^o={180}^o\\ 37+34+x=180\\ 71+x=180\\ x=180-71\\ x=109\end{array}$

  $x={109}^o$
