Answer» ★ given →★ solution →a) what is its COMMON difference?we know that, then, and, now we have two equations, 32 = a + 22d ......(i) 104 = a + 34d ......(ii) now, subtract eq.(i) from eq.(ii) so,common difference of the AP is 6 _________________________b) what is its first term?from first part we get. common difference(d) = 6 now, put the value of d in eq.(i) so, first term of AP is -100 _________________________c) is the difference of any two terms of this SEQUENCE be 90?we know that, common difference of this AP is 6 so, difference of nth term and (n+15)TH term is 90 _______________________________ _______________________________ ✩ for verification ✩ ☞ let n = 1 , then n+15 = 16 from 2nd part we have, now we have to find 16th of this AP now, see difference between these two terms hence, varified! _______________________________ _______________________________ so, we can say yes, here difference of nth term and (n+15)th term of this AP is 90 _________________________d) find the SUM of the first 35 terms?we know that, and here, ・a = -100 ・d = 6 ・n = 35 so, sum of first 35 terms of AP is 70 _________________________hence,

The perimeter of a right triangle is 48 cm and the hypotensue is 18 cm. Find its area |
|
Answer» Answer: The perimeter of a right angled TRIANGLE is 48 cm , and its area is 96 cm² . Length of its hypotenuse is 20 cm . What is the length of the perpendicular sides ? Solution : Let , In a right angled triangle , B ⇔ BASE P ⇔ Perpendicular H ⇔ Hypotenuse Perimeter of a right angled triangle is sum of all its sides , ➳ PER. = B + P + H Hypotenuse , H = 20 cm ➳ Per. = B + P + 20 But it is given Per. = 48 cm , so , ➳ 48 = B + P + 20 ➳ B + P = 28 ➳ P = 28 - B ... (1) Area of a right triangle is , \to \sf A=\dfrac{1}{2}\times b\times h→A= 2 1
×b×h where , h denotes height = perpendicular (P) b denotes base = Base (B) ➠ A = ¹/₂ × B × P Given , Area of the triangle is 96 cm² ➠ 96 = ¹/₂ × B × P ➠ BP = 192 Sub. (1) , ➠ B ( 28 - B ) = 192 ➠ 28B - B² = 192 ➠ B² - 28B + 192 = 0 ➠ B² - 12B - 16B + 192 = 0 ➠ B ( B - 12 ) - 16 ( B - 12 ) = 0 ➠ ( B - 12 ) ( B - 16 ) = 0 ➠ B = 12 ; 16 cm Sub. B VALUE in (1) , ➠ P = 28 - (12) or 28 - (16) ➠ P = 16 or 12 ➠ P = 16 ; 12 cm So , Base of the triangle = 12 or 16 cm \green{\bigstar}★ Perpendicular of the triangle = 16 or 12 cm \pink{\bigstar}★ Length of the perpendicular sides are 12 and 16 cm respectively |
