Show that the points A(1,2,3), B(-1,-2,-3),C(2,3,2),D(4,7,6) are the verticles of parallelogram ABCD,but it is not a rectangle |
|
Answer» Step-by-step explanation: ANSWER Distance between A(1, 2, 3) and B(-1, -2, -1) is AB, =6 Distance between B(-1, -2, -1) and C(2, 3, 2) is BC,
Distance between C(2, 3, 2) and D(4, 7, 6) is CD, =6 The distance between A(1, 2, 3) and D(4, 7, 6) is AD,
Clearly, AB=CD and BC=AD Opposite sides are equal Now, we will find the length of diagonals The distance between A(1, 2, 3) and C(2, 3, 2) is AC,
Distance between B(-1, -2, -1) and D(4, 7, 6) is BD,
Clearly, AC =BD The diagonals are not equal, but opposite sides are equal Thus, Quadrilateral FORMED by ABCD is a parallelogram but not a rectangle |

|
Answer» ANSWER Given : A TRIANGLE ABC. To prove : ∠A+∠B+∠C=180° ⟹∠1+∠2+∠3=180° 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° Thus, the sum of THREE angles of a triangle is 180° I hope it helps u plzz mark as brainlist ✌️✌️☺️❣❣ |

A chord of a circle ofradius 15 cm subtends anangle of 60° at the center areaof the corresponding minorsegment of the circle is20'4478 cm2 |
|
Answer» please follow me Step-by-step explanation: ANSWER In the mentioned figure, O is the centre of CIRCLE, AB is a chord AXB is a major arc, OA=OB= radius = 15 cm Arc AXB subtends an angle 60 o at O. Area of sector AOB= 360 60
×π×r
= 360 60
×3.14×(15) 2
=117.75cm 2
Area of MINOR segment (Area of Shaded region) = Area of sector AOB− Area of △ AOB By trigonometry, AC=15sin30 OC=15cos30 And, AB=2AC ∴ AB=2×15sin30=15 cm ∴ OC=15cos30=15 2 3
=15× 2 1.73
=12.975 cm ∴ Area of △AOB=0.5×15×12.975=97.3125cm 2
∴ Area of minor segment (Area of Shaded region) =117.75−97.3125=20.4375 cm 2
Area of major segment = Area of circle − Area of minor segment =(3.14×15×15)−20.4375 =686.0625cm 2
