Given, Perimeter of triangle = 1020m Let a , b and c be sides of the triangle. So, a + b + c = 1020 or, 20 +b + c = 1020 or, b + c = 1000-------------------- (i) Again, Semi perimeter of the triangle(s)= P /2 .....
Here, 4sin260°+3tan230°-8sin45°cos45° Using their values, we get = 4 (√3/2)2 + 3 (1/√3)2 - 8 (1/√2)(1/√2) = 4(3/4) + 3(1/3) - 8(1/2) = 3 + 1 - 4 = 0 is the required .....

Here, We have given p + 1/p = 4 Cubing both sides, we get (p + 1/p)3 = 43 Using (a + b)3 = a3 + 3ab(a + b) + b3, we get or, p3 + 3p.1/p (p + 1/p) + 1/p3 = 64 or, p3 + 3(4) + 1/p3 = 64 .....
Here, we have given, 4x - 8 ≥ 2 - 4 or, 4x ≥ - 2 + 8 or, 4x ≥ 6 or, x ≥ 6/4 or, x ≥ 3/2 or, x ≥ 1.5 Now, showing in number .....
Here, Distance between a(0,8) and b(a,0) is 2√41 units. Using distance formula, √{(a - 0)2 + (0 - 8)2} = 2√41 Squaring both sides, we get a2 + 82 = 4 x 41 or, a2 = 100 or, a = 10. Thus, the value of a is .....

Here, LHS = Cos20o - sin20o = Cos20o - sin(90o - 70o) = Cos20o - cos70o Using CosC - cosD formula, we get = 2 sin(20o + 70o)/2 .....
We know, 20o = 55o - 35o Take tan of both sides tan20o = tan(55o - 35o) or, tan 20o = (tan 55o - tan 35o)/(1+ tan 55o tan 35o) but ,as 55o + 35o = 90o so tan 35o = cot(90o-35o) = cot 55o tan .....
To prove it we have to use tan(A+B) formula, We know, 70o = 20o + 50o According to the trigonometric identity, tan70o = tan(20o + 50o) or, tan70o= (tan20o + tan50o)/[1 - tan20o tan50o] or, tan70o- .....
