Question

Please help and explain step by step

Answer 1

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 ,

$\begin{cases}\large\bf\red{ \longrightarrow} \rm \:x \: + \: x \: + \: x \: = \: 180 \degree \\ \\ \large\bf\red{ \longrightarrow} \rm \:3x \: = \: 180 \degree \\ \\ \large\bf\red{ \longrightarrow} \rm \:x \: = \: \cancel\frac{180}{3} \\ \\ \large\bf\red{ \longrightarrow} \rm \:x \: = \: 60 \degree \end{cases}$

Answer 2

Answer:

60°

Step-by-step explanation:

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

180/3 = 60
