Question

Find x if PQRS is a parallelogram

Answer 1

Solution:-

$\implies \: \angle \: QRS= \angle \: PRS+ \angle \: PRQ \\ \\ \\ \implies \: \angle \: QRS = 45 \degree + 70 \degree \: \\ \\ \\ \implies \: \angle \: QRS = 115 \degree \\ \\ \\ \\ \implies \: \angle \: QRS + \angle \:PSR = 180 \degree$

sum of parallel line interior angle

$\implies \: 7x - 5 + 115 = 180 \\ \\ \\ \implies \: 7x + 110 = 180 \\ \\ \\ \implies \:7x = 180 - 110 \\ \\ \\ \implies \: x = \cancel{\frac{70}{7} } \\ \\ \\ \implies \: x = 10$
