A) \[72{}^\circ \]
B) \[45{}^\circ \]
C) \[54{}^\circ \]
D) \[27{}^\circ \]
Correct Answer: D
Solution :
Suppose the angles of a pentagon are x, 2x, 3x, 5x and 9x. Then, \[x+2x+3x+5x+9x=(5-5)\times 180{}^\circ \] \[20x=3\times 180{}^\circ \] \[x=27{}^\circ \] Hence, the smallest angle is\[27{}^\circ \]You need to login to perform this action.
