Point D,E are taken on the side BC of an acute angled triangle ABC,, such that `BD = DE = EC`. If `angle BAD = x, angle DAE = y and angle EAC = z` then the value of `(sin(x+y) sin (y+z))/(sinx sin z)` is ______

Points D,E are taken on the side BC of a triangle ABC, such that BD=DE=EC. IF angle BAD=x, angle DAE=y, angle EAC=z , then the value of (sin(x+y)sin (y+z))/(sinx sin z) =

In Delta ABC BC bot AC at D.E is a point on BC such that angle BEA = x^(@) If angle EAC = 36^(@) and angle EBD = 40^(@) , then the value of x is:

Let D and E be two points on the side BC of triangle ABC such that AD = AE and angle BAD = angle EAC . If AB = (3x+1)cm , BD = 9cm , AC = 34cm and EC = (y + 1) cm, then the value of (x + y) is: triangle ABC में, D और E भुजा BC पर दो बिंदु इस प्रकार है की AD = AE और angle BAD = angle EAC । यदि AB = (3x +1) cm, BD = 9cm, AC = 34cm और EC = (y+1) cm है, तो (x + y) का मान है

In a triangle ABC, points D and E are taken on side BC such that BD= DE= EC. If angle ADE = angle AED = theta , then: (A) tan theta = 3 tan B (B) 3 tan theta = tan C

In a triangle ABC, points D and E are taken on side BC such that BD=DE=EC. If angle ADE = angle AED=theta, then: (A)tan theta=3tan B(B)3tan theta=tan C

In the figure, D and E are the points on sides AB and AC of triangle ABC such that DE || B C. " if "angle B = 30^(@) and angle A = 40^(@), find (i) x (ii) y (iii) z

If sin x+ sin y+ sin z=3, then the value of (cos x+ cos y+ cos z) is-

Find the values of the angles x,y and z

In a triangle ABC, points D and E are taken on side BC such that BD= DE= EC. If angle ADE = angle AED = theta , then: (A) tan theta = 3 tan B (B) 3 tan theta = tan C (C) (6tan theta )/( tan^2 theta -9)= tanA (D) angleB = angle C
