math formulas important varsha se - Class 10 Board Exam Levell Questions ( Maths) Question 1 Question 2 Solve the quadratic equation = 2 sec? A Prove that 7*+3=0 by using qundratic formula , 2*2 १+sinA 1- sin A Solution: Solution Here এ = 2 b = -7 c= 3 LHS = 2 sec A 1+sinA 1-sin 4 2b + Y62 4ac X= (1-sin 4 + 1 + sin 4) Sin2 గ 7+ /49-24 X =2 7+5 Cos'A >= sec A 2 2 Solutions: X = 3x 2 LHS = RHS 8 Hence Proved Question 4 Question 3 Find the value of kif the quadratic equation Find the distance between the points 6x + 9 = 0 has A(3, 4) and B(7 १०) K2' roots: equal Solution Solution Y(X2' For roots D= 0 Distance =X1)2 + (2 Y1)2 equall 62' Aac = 0 =Y(7 - 3)? + (10 - 4)2 (-6)2 4k( 9) = 0 942 + 62 36 36k = 0 916 + 36 -36< =-36 /52 = 2/13 units k = 1. Distance = 213 units K = 1 Question 6 Question 5 probability Find the height of ೩ tower if its shadow is 24 m' A die is thrown once. Find the' and the angle of elevation of the top is 452 long of getting numper prirne' Solution Solution: Prime numbers on Let height of the tower be h die: 2,3,5. Pgetting 45% = prime) tan 24 1=h 24 m 24 Probability 6m Height of the tower 24 m Class 10 Board Exam Levell Questions ( Maths) Question 1 Question 2 Solve the quadratic equation = 2 sec?
