Answer 1

Step-by-step explanation:

3x +20 + 4x -36 = 180

7x -16 = 180

7x = 196

x =28

Answer 2

$\sf ∠POR + ∠ROQ = 180° \\ \\ \sf→(3x+20)° + (4x - 36)°= 180° \\ \\ \sf→3x + 4x + 20°-36° = 180 \\ \\ \sf →7x = 180°+16° \\ \\ \sf → \: \: \: \: x = \frac{196°}{7} \\ \\ \: \: \: \pink{\sf →x = 28°}$
