Question

find the angles marked with small letters in the diagrams below.

Explanation:

Step1: Identify angle - relationship

Since $MN\parallel OP$, the given $49^{\circ}$ angle and angle $x$ are corresponding angles.

Step2: Determine the value of $x$

Corresponding angles formed by parallel lines are equal. So $x = 49^{\circ}$.

Answer:

$49^{\circ}$
