Question

In the given figure, $\angle ABC={35}^{\circ }$.

The value of $\angle ACB$ is

• A. ${55}^{\circ }$
• B. ${50}^{\circ }$
• C. ${45}^{\circ }$
• D. ${54}^{\circ }$

Answer 1

The correct option is A ${55}^{\circ }$

Given,
$\angle ABC={35}^0$
$\angle BAC={90}^0$(Angle in a semi circle is right angle)
$Sumofallanglesin△ABC=180$
$\angle ABC+\angle BAC+\angle ACB={180}^0$
$\angle 35+\angle 90+\angle ACB={180}^0$
$\angle ACB=180-125={55}^0$
