Question

In the given triangle, the value of $x$ is

• A. ${55}^o$
• B. ${110}^o$
• C. ${70}^o$
• D. ${27.5}^o$

Answer 1

The correct option is D ${27.5}^o$

In the given triangle the two sides are equal therefore the corresponding angles are also equal

$\Rightarrow 2x={55}^{\circ }$,$x={27.5}^{\circ }$
