In right angled triangle, \(\angle\text{A}\) is right angle and \(\angle\text{B} = 35^\circ\), then \(\angle\text{C}\) is.
1 65°
2 55°
3 75°
4 45°
Explanation:
55° Let the right angled triangle by \(\triangle\text{ABC}\), Then \(\angle\text{A} = 90^\circ,\angle\text{B} = 35^\circ\) [Given] \(\angle\text{A} + \angle\text{B} +\angle\text{C} = 180^\circ\) [Sum of all the angles of the triangle is 180°] \(\Rightarrow 90^\circ +35^\circ + \angle\text{C} = 180^\circ \Rightarrow \angle\text{C} = 180^\circ - 125^\circ = 55^\circ\)
