3. In a quadrilateral ABCD, equal diagonals AC andBD intersect at P, such that AP = PC and BP = PD,also ZBPC = 90°, then quadrilateral is exactly(a) a parallelogram (b) a squarea rhombus(a rectangle |
|
Answer» Answer: (b) square Step-by-step explanation: ⇒ In given figure ABCD is a square having all sides are equal and opposite sides parallel to each other. AC and BD are diagonals. ⇒ In △ABC and △BAD, ⇒ AB = AB [Common line] ⇒ BC = AD [Sides of square are equal.] ⇒ ∠ABC = ∠BAD [All four angles of square is 90 ∘ ] ⇒ △ABC ≅ △BAD [By SAS PROPERTY] ⇒ In a △ OAD and △OCB, ⇒ AD = CB [sides of a square] ⇒ ∠OAD = ∠OCB [Alternate angle] ⇒ ∠ODA = ∠OBC [Alternate angle] ⇒ △OAD ≅ △OCB [By ASA Property] ⇒ So, OA = OC ----- ( 1 ) ⇒ Similarly, OB = OD ------ ( 2 ) From ( 1 ) and ( 2 ) we get that AC and BD bisect each other. ⇒ Now, in △OBA and △ODA, ⇒ OB = OD [From ( 2 )] ⇒ BA = DA ⇒ OA = OA [Common line] ⇒ ∠AOB + ∠AOD ----- ( 3 ) [By CPCT] ⇒ ∠AOB + ∠AOD = 180 ∘ [Linear pair] ⇒ 2∠AOB = 180 ∘
∴ ∠AOB = ∠AOD = 90 ∘
∴ We have proved that diagonals of square are equal and perpendicular to each other. |

There are 50 coins of two different denominations, two-rupee and five-rupee, in a box. If the number oftwo-rupee coins is 10 less than that of five-rupee coins, find the number of coins of each denominationAlso, find the amount in the boxPanin if they together scored 15 point |
|
Answer» Step-by-step explanation: LET the no of Rs 2 COINS be x and the no of Rs 5 coins be y. x + y = 36 … (1) 2x + 5y = 84 … (2) Multiplying (1) by 2 : 2x + 2y = 72 … (3) Subtracting (3) from (2) : => 2x + 5y - 2x - 2y = 84 - 72 => 3y = 12 => y = 4 So, the no of Rs 5 coins are 4.

A train runs 120km in West direction, 30km in South direction and then 80km In east direction before reaching the station. in which direction is the station from the trains starting point? |
|
Answer» Answer: Step-by-step explanation: The train is 50 km south -WEST of its starting point You NEED to draw the lines or the diagram as the direction of train. So, now as train goes 120km in west ,30 km in south and again 80 km in EAST direction, connect the points from where it starts to where it ends. You will get a right angle triangle so now we KNOW two sides of that triangle i.e. 30km and 40 km. So, now using Pythagoras theorem we get distance as 50km south-west. |
