Sia ? 4 years ago

NUMBER OF GOOD ORANGES = TOTAL NUMBER OF ORANGES - NUMBER OF ROTTEN ORANGES

300-30=270

THEREFORE THE NUMBER OF GOOD ORANGES ARE 270

PERCENTAGE OF GOOD ORANGES =270/300×100 =90

THEREFORE THE PERCENTAGE OF GOOD ORANGES IS 90%.

Given : A triangle ABC. To prove : ∠A+∠B+∠C=180 o ⟹∠1+∠2+∠3=180 o Construction : Through A, draw a line l parallel to BC. Proof : Since l∥BC. Therefore, ∠2=∠4 .......eq(i) And, ∠3=∠5......eq(ii) adding eq(i)and(ii) Therefore, ∠2+∠3=∠4+∠5 ∠1+∠2+∠3=∠1+∠4+∠5 [adding∠1bothSide] ∠1+∠2+∠3=180 o Thus, the sum of three angles of a triangle is 180 o .
