Step-by-step explanation:
hlo mate here's your answer
Solution:
(i) In Fig (i),
x = y (Angles opposite to equal sides)
But x + y + 80° = 180° (Angles of a triangle)
⇒ x + x + 80° = 180°
⇒ 2x = 180° - 80° = 100°
⇒ x = 100°/2 = 50° ∴ y = x = 50°
Hence x = 50°, y = 50°
(ii) In Fig. (ii),
b = 40° (Angles opposite to equal sides)
But a + b + 40° = 180°
(Angles of a triangle)
⇒ a + 40° + 40° = 180°
⇒ a + 80° = 180°
⇒ a = 180° - 80° = 100°
Hence, a = 100° , b = 40°
(iii) In Fig. (iii)
x = y (Angles opposite to equal sides)
But x + y + 90° = 180°
(Angles of a triangle)
⇒ x + x + 90° = 180°
⇒ 2x + 90° = 180°
⇒ 2x = 180° - 90° = 90°
∴ x = 90°/2 = 45° ∴ y = x = 45°
Hence x = 45°, y = 45°
(iv) In Fig. (iv),
a = b (Angles opposite to equal sides)
But a + b + 80° = 180°
⇒ a + a + 80° = 180°
⇒ 2a = 180° - 80° = 100°
⇒ a = 100/2 = 50 ∴ b = a = 50°
x = a + 80°
I hope its help you mark as brainlist plz
