In the triangle ABC, If AB = BC = AC, theni: x ii: y
Correct answer: B. (ii) is greater
- A. (i) x is greater
- B. (ii) is greater
- C. Both are equal
- D. Can't be determined
Explanation
if AB = BC = AC i.e all the three sides of triangle are equal,the triangle is equilateral, all three angles are supposed to be equal. If the one angle mentioned is 60° than the other two should also be 60°53°+x= 60X= 7°72-y=60°Y=12°Option B is correct as (ii)Y is greater than (i) X (12>7)Option A: Not correct as x is smaller than yOption C: X and y are not equal as x= 7 and y=12Option D: The value can be determined as shown in calculation above
