Answer:
x = 119
Explanation:
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.
<BCD is an exterior angle of triangle ABC, measuring x.
The remote interior angles of <BCD are <A and <B.
By the theorem above, m<BCD = m<A + m<B
x° = 52° + 67°
x = 119
