IF the lengths of the side of triangle are `3,5A N D7,` then the largest angle of the triangle is `pi/2` (b) `(5pi)/6` (c) `(2pi)/3` (d) `(3pi)/4`

If the lengths of the sides of a triangle are 3, 5, 7 , then its largest angle of the triangle is

If the angles of a triangle are in A.P.then the measures of one of the angles in radians is (pi)/(6) b.(pi)/(3) c.(pi)/(2) d.(2 pi)/(3)

cot^(-1)(-sqrt3)= (a) -pi/6 (b) (5pi)/6 (c) pi/3 (d) (2pi)/3

In the sides of a triangle are in the ratio 1:sqrt(3):2, then the measure of its greatest angle is (pi)/(6)(b)(pi)/(3)(c)(pi)/(2)(d)(2 pi)/(3)

The period of cos5 theta is (a) pi^(2) (b) 2 pi (c) 2 pi/5 (d) pi/3

In a right angled triangle the hypotenuse is 2sqrt(2) xx the perpendicular drawn from the opposite vertex.Then the other acute angles of the triangle are (a) (pi)/(3)and(pi)/(6) (b) (pi)/(8)and(3 pi)/(8) (c) (pi)/(4) and (pi)/(4) (d) (pi)/(5) and (3 pi)/(10)

In a triangle ABC the angle B is greater than angle C. If the measure of angles B and C satisfy the equation 4sin^3x-3sinx+0.75=0 then the measure of angle A is (A) pi/2 (B) (2p)/3 (C) pi/6 (D) (5pi)/6

In any triangle ABC,sin A-cos B=cos C, the angle B is a.(pi)/(2) b.(pi)/(3) c.(pi)/(4) d.(pi)/(6)

cos^-1 {-sin((5pi)/6)}= (A) - (5pi)/6 (B) (5pi)/6 (C) (2pi)/3 (D) -(2pi)/3
