Question

In rhombus ABCD. If $\angle A={74}^{\circ }$, find $\angle B$.

• A. ${100}^o$
  
• B. ${104}^o$
• C. ${106}^o$
• D. ${108}^o$

Answer 1

The correct option is C ${106}^o$

In rhombus ABCD,

We know that adjacent angles in a rhombus are supplementary.

$\angle A+\angle B={180}^{\circ }$

${74}^{\circ }+\angle B={180}^{\circ }$

$\angle B={180}^{\circ }-{74}^{\circ }={106}^{\circ }$
