Answer 2

${\Large{\underbrace{\underline{\sf{Understanding\;the\; Question}}}}}$

Here in this question we have given 2 angles of triangle measures 30° and 122° respectively and we have to find value of angle x.

$\rule{300}{2}$  

So let's apply Angle Sum Property of ∆

In ∆TUS

∠T+∠U+∠S=180°

⇒ 122°+x+30°=180°

⇒ x=180°-122°-30°

⇒ x=28°.

∴The required angle is 28°.
