Answer 1

Answer :

➥ Given :

• AD ll BC and AB ll DC

• So its an parallelogram

➥ Step-by-Step explanation :

step-1 :

• finding a :

• ⇒ a + 110 + 30 = 180°

• ⇒ a + 140 = 180°

• ⇒ a = 180 - 140

• ⇒ a = 40°

step-2 :

• ↣ 70 + a = a + d

• we know a is 40° so,

• ↣ 70 + 40 = 40 + d

• ↣ 110 = 40 + d

• ↣ d = 110 - 40

• ↣ d = 70°

step-3 :

• lets find b and c

• b + c = 180 - (70 + a)

• b + c = 180 - (70 + 40)

• b + c = 180 - 110

• b + c = 70°

• c + a + 110 = 180°

• c + 40 + 110 = 180°

• c + 150 = 180°

• c = 180 - 150

• c = 30°

• b + c = 70°

• b + 30 = 70°

• b = 70 - 30

• b = 40°

∴ a = 40° , b = 40° , c = 30° , d = 70°
