AB||DC and AD||BC if DAB is 75 find the measures of a b cgive answer by step by step |
|
Answer» AB ║ DC and AD ║ BCand, ∠DAB = 75°Solution:-Here, AD ║ BC and AB is transversal∵ CONSECUTIVE interior angles are supplementary∴ ∠DAB + ∠ABC = 180° [ AD ║ BC and they are Consecutive interior angles ]so, 75° + ∠ABC = 180°⇒ ∠ABC = 180° - 75°⇒ ∠ABC = a = 105°Now, AB ║ DC and BC is transversal∵ Consecutive interior angles are supplementary∴ ∠DCB + ∠ABC = 180° [ AB ║ DC and they are Consecutive interior angles ]so, ∠DCB + 105° = 180°⇒ ∠DCB = 180° - 105°⇒ ∠DCB = b = 75°Now, AD ║ BC and DC is transversal∵ Alternate interior angles are Equal in measure∴ ∠DCB = ∠EDC [ AD ║ BC and they are Alternate interior angles ]⇒ ∠EDC = C = 75°Hence, a = 105° and b = c = 75°Some important TERMS:-When two parallel lines intersected by a transversal then:-Alternate interior angles are equal.Alternate EXTERIOR angles are equal.Corresponding angles are equal.Consecutive interior angles are supplementary.Vertically opposite angles are equal. |

An iron pipe 20cm long has exterior diameter equal to 25cm.if the thickness of the pipe is 1cm , the pipe is to be painted red on all its faces . find the area to be painted. |
|
Answer» : Total surface area of pipe is 3168 cm²Given :height of pipe = 20cmExternal diameter = 25cmTo find :Area Solution :Given that height is 20CM , External diameter is EQUAL to 25cm . if the thickness of the pipe is 1cm so pipe painted red on all the faces . so we have to find the external radius and INTERNAL radius then after we have to use the formula of total surface area then we get the total surface area of pipe External diameter = 25cmExternal radius = 25/2 = 12.5 cmInternal diameter = 25 - (1 + 1) = 23 cmInternal radius = 23/2 = 11.5 cmLet the external radius be RLet the internal radius be RAS we know that :TSA of the pipe = 2πh(R + r) + 2π(R²+r²)TSA means total surface areawhere h is 20cm , R is 12.5cm , r is 11.5cm ⟿ 2 × 22/7 × 20(12.5 + 11.5) + 2 x 22/7(12.5² + 11.5²)⟿ (44 × 480)/7 + (44 × 24)/7⟿ 21120/7 + 1056/7⟿ 22176/7⟿ 3168cm²Hence , Total surface area of pipe is 3168 cm² |

Prove that diagonals of a square are equal? |
|
Answer» Step-by-step explanation:Let ABCD be a square. Let the diagonals AC and BD intersect each other at a point O. To prove that the diagonals of a square are equal and BISECT each other at right angles, we have to prove AC = BD, OA = OC, OB = OD, and AOB = 90º. In ABC and DCB, AB = DC (Sides of a square are equal to each other) ABC = DCB (All interior angles are of 90) BC = CB (Common side) ABC = DCB (By SAS congruency) AC = DB (By CPCT) Hence, the diagonals of a square are equal in length. In AOB and COD, AOB = COD (Vertically opposite angles) ABO = CDO (Alternate interior angles) AB = CD (Sides of a square are always equal) AOB = COD (By AAS congruence rule) AO = CO and OB = OD (By CPCT) Hence, the diagonals of a square bisect each other. In AOB and COB, As we had proved that diagonals bisect each other, therefore, AO = CO AB = CB (Sides of a square are equal) BO = BO (Common) AOB = COB (By SSS congruency) AOB = COB (By CPCT) However,AOB + COB = 180 (Linear pair) 2 AOB = 180º AOB = 90º Hence, the diagonals of a square bisect each other at right angles. |
