What is the use of horizontal line of right angle triangle in height and distance. Give two example5. What is the use of incline decline of right angle triangle in height and distance. Give two example.6. Make the chart of some specific specific angle of t-ratio.[0",30,45,60", |
|
Answer» Answer: (≧▽≦)(≧▽≦) (≧▽≦)(≧▽≦)The angle of elevation is when you are measuring the angle from the floor or the ground, and the angle of depression is when you are measuring from a ceiling. The only time the two angles are equal is if the ceiling and floor are parallel with each other.
Observe the figure. Consider the observer to be at point C. The height of the object is shown by line AB. The distance of the object from the observer is given by line BC. The object may or may not be PERPENDICULAR to the ground. Line AC REPRESENTS the Line of Sight when the observer is observing the topmost point of the object. Angle α represents the angle of elevation and Angle β represents the angle of depression |

Quadratic Equations Exercise 5A – Selina Concise Mathematics Class 10 ICSE Solutions Find which of the following equations are quadratic: Solution 1(i) (3x – 1)2 = 5(x + 8) ⇒ (9X2 – 6x + 1) = 5x + 40 ⇒ 9x2 – 11x – 39 =0; which is of the form ax2 + bx + c = 0. ∴ Given equation is a quadratic equation. Solution 1(ii) 5x2 – 8x = -3(7 – 2X) ⇒ 5x2 – 8x = 6x – 21 ⇒ 5x2 – 14x + 21 =0; which is of the form ax2 + bx + c = 0. ∴ Given equation is a quadratic equation. Solution 1(iii) (x – 4)(3x + 1) = (3x – 1)(x +2) ⇒ 3x2 + x – 12x – 4 = 3x2 + 6x – x – 2 ⇒ 16x + 2 =0; which is not of the form ax2 + bx + c = 0. ∴ Given equation is not a quadratic equation. mark as Brainliest #Thanks |

WhyQ1.A wire is in the shape of a square of side 10 cm. If the wire is rebent into a rectangle of length 13 cm, find its breadth. Which shape encloses more area? |
|
Answer» Answer: Let a be the SIDE of a square, l be the length and B be the BREADTH of rectangle. As length of wire is constant, perimeter of both SHAPES would be same, ⇒4a=2(l+b) ⇒40=2(12+b) ⇒b=18 cm Area of square=a 2 =10 2 =100cm 2
Area of rectangle=lb=12×18=216cm 2
⇒ Area of rectangle is greater by 116cm 2 . Step-by-step explanation: Thank my answer and mark me as brainist |
