The angle sum property of a triangle:

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°

$\underline {\mathcal {{{\color{orange}{\bf \large \rightarrow \: \angle \: 1 \: + \: \angle \: 2 \: + \: \angle \: 3 \: = \: 180 \degree}}}}}$

${\large\begin{gathered} { \underbrace{\boxed { \rm {\blue {Solution}}}}}\end{gathered}}$

In 1st Triangle

• ∠1 = 50°
• ∠2 = 70°
• ∠3 = x

.

$\bf \large\longrightarrow \: \: 50 \degree \: + \: 70 \degree \: + \: x \: = \: 180 \degree$

$\bf \large\longrightarrow \: \:120 \degree \: + \: x \: = \: 180 \degree$

$\bf \large\longrightarrow \: \: x \: = \: 180 \degree \: - \: 120 \degree$

$\bf \large\longrightarrow \: \: x \: = \: 60\degree$

_______________________

In 2nd Triangle

• ∠1 = x
• ∠2 = 60°
• ∠3 = 60°

$\bf \large\longrightarrow \: \: x \: + \: 60 \degree \: + \: 60 \degree \: = \: 180 \degree$

$\bf \large\longrightarrow \: \: x \: + \: 120 \degree \: = \: 180 \degree$

$\bf \large\longrightarrow \: \: x \: = \: 180 \degree \: - \: 120 \degree$

$\bf \large\longrightarrow \: \: x \: = \: 60\degree$
