Question

Please help and explain step by step

Answer 1

60°

Explanation:

All side are equal, Sum of all angle in traingle is 180

180/3 = 60

Answer 2

The angle sum property of a triangle :

• The sum of the interior angles of a triangle is 180°.
• This property of a triangle is true for all triangles.

So ,

`\begin{cases}\large\bf\red{ \longrightarrow} \rm \:x \: + \: x \: + \: x \: = \: 180 \degree \\ \\ \large\bf\red{ \longrightarrow} \rm \:3x \: = \: 180 \degree \\ \\ \large\bf\red{ \longrightarrow} \rm \:x \: = \: \cancel(180)/(3) \\ \\ \large\bf\red{ \longrightarrow} \rm \:x \: = \: 60 \degree \end{cases}`
