Question

Measure of an angle of linear pair is ${125}^{\circ }$, then what is the measure of another angle?

• A. ${55}^{\circ }$
• B. ${75}^{\circ }$
• C. ${65}^{\circ }$
• D. ${45}^{\circ }$

Answer 1

Answer: (A)

${55}^{\circ }$

Let another angle be 'X'

$x+{25}^0={180}^0$

$x={180}^0-{125}^0$

$x={55}^0$

Hence, another angle $={55}^0$
