Answers:
(6) ∠1 + ∠2 = 180° (Linear pair)
⇒ 50 + ∠2 = 180
⇒ ∠2 = 180 - 50
⇒ ∠2 = 130°
⇒ ∠5 = 50° (Corrosponding angles)
(7) Square root of 441
3 | 441
7 | 147
7 | 21
3
⇒ 441 = 7² × 3²
⇒ 441 = 21²
⇒ Square root of 441 is 21
(8) ∠1 = ∠2
But ∠1 + ∠2 = 180°
⇒ ∠1 + ∠1 = 180°
⇒ 2 × ∠1 = 180°
⇒ ∠1 = = 90°
⇒ ∠1 = ∠2 = 90°
