Answer 2

Answer:

$we \: know \: that \: the \: sum \: of \: adjacent \: side \: of \: pallelogrm \: is \: 180 \\ {\implies}{ \boxed{\mathbb{\pink{therefore}}}} \\ 3y + 10 + 3y - 4 = 180 \\ 6y + 6 = 180 \\ 6y = 180 - 6 \\ y = \frac{174}{6} \\ y = 29 \\ 3y + 10 = 3 \times 29 + 10 = 97 \degree \\ 3y - 4 = 3 \times 29 - 4 = 83 \degree \\ {\implies}{ \boxed{\mathbb{\red{therefore \: the \: four \: angle \: of \: pallelogram \: is}}}} \\ \: 97 \degree \\ 83 \degree \: \\ 97 \degree\\ 83 \degree \\ \\{\implies}{ \boxed{\mathbb{\blue{ hope \: it \: help \: ful \: for \: you \: sister}}}}$
