MCQ
Mark $(\checkmark)$ against the correct answer.In a $\triangle\text{ABC}$ it is given that $\angle\text{B}=37^\circ$ and $\angle\text{C}=29^\circ$ Then, $\angle\text{A}={}?$
  • A
    $86^\circ$
  • B
    $66^\circ$
  • ✓
    $114^\circ$
  • D
    $57^\circ$
✓

Answer

Correct option: C.
$114^\circ$
In $\triangle\text{ABC},\angle\text{B}=90^\circ,\angle\text{G}=29^\circ$
But $\angle\text{A}+\angle\text{B}+\angle\text{C}=180^\circ ($angles of a triangle$)$
$\Rightarrow\angle\text{A}+37^\circ+29^\circ=180^\circ$
$\Rightarrow\angle\text{A}+66^\circ=180^\circ$
$\Rightarrow\angle\text{A}=180^\circ-66^\circ=114^\circ$
