A) \[142.5{}^\circ \]
B) \[180{}^\circ \]
C) \[172.3{}^\circ \]
D) \[129.9{}^\circ \]
E) \[152.2{}^\circ \]
Correct Answer: A
Solution :
(2+3+5 +6) \[=360{}^\circ \] or, \[16\equiv 360{}^\circ \] \[\therefore 1\equiv 22.5{}^\circ \] Second largest angle \[=5\times 55.5=112.5{}^\circ \] Smaller angle of the parallelogram \[=\frac{1}{3}\times 112.5{}^\circ =37.5{}^\circ \] \[\therefore \]Adjacent angle\[=180{}^\circ -37.5{}^\circ =142.5{}^\circ \]You need to login to perform this action.
