Question

In a right angled triangle if an angle measures ${35}^{\circ }$ then the measure of other angle is

• A. ${65}^{\circ }$
• B. ${55}^{\circ }$
• C. ${45}^{\circ }$
• D. ${30}^{\circ }$

Answer 1

Answer: (B)

${55}^{\circ }$

In a right angle triangle,

One angle is ${90}^{\circ }$

Sum of interior angles $={180}^o$

$\Rightarrow 35+x+90={180}^o$

$\Rightarrow x={55}^o$
