Q:
A) 138 to 164 | B) 125 to 147 |
C) 148 to 158 | D) 152 to 164 |
Answer: D) 152 to 164
Explanation:
Explanation:
A+7B=112
it is clear that A = 14, then it becomes A>=B, but A is smallest angle) given
so, range of A is 0.0001 to 13.9999 ( I am taking upto 4 decimal places)
so, range of B becomes 14 to 16 ( after rounding off to 4 decimal places)
so, range of C becomes 152 to 164 ( after rounding off to 4 decimal places)
