A) \[{{37}^{o}}\]
B) \[{{27}^{o}}\]
C) \[{{17}^{o}}\]
D) \[{{7}^{o}}\]
Correct Answer: A
Solution :
Given, the angles \[{{(2a-10)}^{o}}\] and \[{{(a-11)}^{o}}\] are complementary angles. \[\therefore \] \[{{(2a-10)}^{o}}+{{(a-11)}^{o}}={{90}^{o}}\] \[\therefore \] \[a={{37}^{o}}\]You need to login to perform this action.
