Chapter 4: Q1. (page 146)

For the following figure, find the value of $x$ .

Short Answer

Expert verified

The value of $x = 70^{\circ}$ .

Step by step solution

Step 1- Check the figure.

Consider the figure.

Step 2- Apply the concept of triangle.

Properties of triangle states that opposite to congruent sides are congruent angles and sum of the three angles is equal to 180 degrees.

Step 3- Step description.

From the figure, $x^{\circ}, x^{\circ}, 40^{\circ}$ be the three angles of the triangle.

Since the sum of angles is equal to 180 degrees then find the value as follows:

$\begin{array}{l} x + x + 40 = 180 \\ 2 x + 40 = 180 \\ 2 x = 140 \\ x = 70 \end{array}$

Therefore, the value is $x = 70^{\circ}$ .
