A) \[{{30}^{o}},\,\,{{60}^{o}},\,\,{{90}^{o}}\]
B) \[{{90}^{o}},\,\,{{60}^{o}},\,\,{{30}^{o}}\]
C) \[{{30}^{o}},\,\,{{90}^{o}},\,\,{{60}^{o}}\]
D) \[{{45}^{o}},\,\,{{90}^{o}},\,\,{{45}^{o}}\]
Correct Answer: B
Solution :
\[\angle A:\angle B:\angle C=\frac{1}{2}:\frac{1}{3}:\frac{1}{6}\] \[\Rightarrow \]\[\angle A:\angle B:\angle C=3:2:1\] \[\therefore \]\[\angle A={{90}^{o}},\angle B={{60}^{o}},\angle C={{30}^{o}}\]You need to login to perform this action.
