Question

5. The adjacent angles of a parallelogram are
(3x – 12) and (52 + 2x)º. Find the angles of the
parallelogram.​

Answer 1

$\huge{\underline{\bf{AnsWer :}}}$

As we know what adjacent angles are equal to 180°

According to the question :

➡ (2x - 12)° + (52 + 3x)° = 180°

➡ 2x - 12 + 52 + 3x = 180

➡ x + 40 = 180

➡ x = 180 - 40

➡ x = 140°

Therefore

The angles are :

➡(2x - 12)° = 72°

➡(52 - 3x)° = 108°
