Line m is parallel to line n. Line m is above line n. A transversal line cuts both parallel lines. The obtuse upward right angle made by the transversal line with line m is labeled as 115 degrees. The acute downward right angle made by the transversal line with line m is labeled as 65 degrees. The acute downward right angle made by the transversal line with line n is labeled as left parenthesis 3 x plus 5 right parenthesis degrees.
The answer is that x = 20. Lines m and n are parallel and angles on
equivalent sides of a traversal of parallel lines are equal, therefore and as it is acute angle ( an angle that is less than 90°), So
