The sides of a right-angled triangle containingthe right angle are 4x cm and (2x - 1) cm. Ifthe area of the triangle is 30 cm2; calculate thelengths of its sides. |
|
Answer»
Area of triangle = 1/2 ×base × height
➝ 30 = 1/2 ×4x × (2x -1) ➝ 30 × 2 = 4x × (2x -1) ➝ 60 = (4x)(2x-1) ➝ 60/4 = x(2x-1) ➝ 15 = 2x² - x ➝ 2x² - x -15 = 0 Now solving EQUATION for x ➝ 2x² - 6x + 5x -15 ➝ 2x (x - 3) +5(x - 3) ➝ (2x + 5) (x -3)
Length of any side cannot be negative . So, x = 3 Base = 4x ⠀⠀⠀⠀ = 12cm Height = 2x-1 ⠀⠀⠀⠀⠀ = 5 cm we know that , according to question the triangle is RIGHT angled triangle. So, hypotenuse² = base² + perpendicular² ➝ H² = 12² +5² ➝ H² = 144 +25 ➝ H² = 169 ➝ H = √169 ➝ H = 13, So, All sides of triangle are 12 cm , 5cm ,and 13cm ━━━━━━━━━━━━━━━━━━━━━━━━━ |

What must be substract from x^3+4x^2+6x-6 to obtain x^3+5x^2+9x-7 ? |
|
Answer» Answer: LET y must be subtracted from x^3+4x^2+6x-6 to obtain x^3+6x^2+9x-7 then , x^3+4x^2+6x-6 - y = x^3+6x^2+9x-7 -y = x^3+6x^2+9x-7 - (x^3+4x^2+6x-6) -y = x^3+6x^2+9x-7-x^3-4x^2-6x+6 -y = x^3-x^3+6x^2-4x^2+9x-6x-7+6 -y = 2x^2+3x-1 -y = -(-2x^2-3x+1) y = -2x^2-3x+1 therefore -2x^2-3x+1 must be subtracted from x^3+4x^2+6x-6 to obtain x^3+5x^2+9x-7 if you get the right answer then hit the THANKS BUTTON and follow me |

If the area of a rhombus is 96 cm cube and one of its diagonal is 12 cm long, find the length of the other diagonal. Also, find its perimeter. |
|
Answer» ⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐ We know that,
LET the second diagonal be D. So, ACCORDING to the problem, 96 = 1/2 × 12 × D => 6D = 96 => D= 96/6 = 16 cm.
Side of a rhombus = √(8²+6²) = √100 = 10 cm So, Perimeter = 10+10+10+10 = 40 cm. ⭐⭐⭐ ALWAYS BE BRAINLY ⭐⭐⭐ |
