Question

What is the size of angle BAC?​

Answer 1

76°

Explanation:

ABC is an Isosceles triangle and angle ABC is given as 52°

since xy is parallel to BC we can conclude that ACB is also 52°

The sum of interior angles in a triangle is equal to 180°

52° + 52° + BAC = 180°

104° + BAC = 180°

BAC = 76°
