Solve the triangle ABC if `a=5`, `b=4` and `angle A``=60^(@`, then side `c` is

Find the angle A in triangle ABC, if angle B=60^∘ and angle c=70^∘

In a triangle ABC if angle ABC=60^(@) , then ((AB-BC+CA)/(r ))^(2)=

PQ is a vertical tower having P as the foot. A,B,C are three points in the horizontal plane through P. The angles of elevation of Q from A,B,C are equal and each is equal to theta . The sides of the triangle ABC are a,b,c, and area of the triangle ABC is del . Then prove that the height of the tower is (abc) tantheta/(4)dot

In Delta ABC , right angle is at B,AB = 5cm and angle ACB =30^(@) Determine the lengths of the sides BC and AC.

If in a triangle ABC , a=5,b=4 ,A = (pi)/( 2) +B then C

In a triangle ABC, angleA =60^o ,angleC =30^o ,b=2sqrt3,c=2 then a is:

In a triangle ABC , if angle A=60 , a=5,b=4 then c is a root of the equation

In Delta ABC, if a = sqrt(3) - 1, b = sqrt(3) + 1 and angleC = 60^(@) , find the other side and the other two angles.
