A) \[108{}^\circ \],\[72{}^\circ \]
B) \[72{}^\circ \], \[36{}^\circ \]
C) \[100{}^\circ \], \[80{}^\circ \]
D) \[144{}^\circ \], \[36{}^\circ \]
Correct Answer: A
Solution :
Let the angles be 3x and 2x. We have, \[3x\text{ }+\text{ }2x\text{ }=\text{ }180{}^\circ \] \[5x\text{ }=\text{ }180{}^\circ \] \[x\text{ }=\text{ }36{}^\circ \] \[\therefore \] The angles are \[36\times 3,\,\,36\times 2={{108}^{\text{o}}},\,{{72}^{\text{o}}}\]You need to login to perform this action.
