In triangle `ABC` (with the usual notation), angle `A = 36^@,` side `b = 10` and side `c=12.` Without using cosine formula to find side`(a)`

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

In Delta ABC with usual notation, (c-b cos A)/(a) is equal to

In any triangle ABC, the side are a=7,b=5 and c=8. Find A.

If in a triangle ABC, in the usual notation, 2a cos ((B-C)/(2))=b+c and Be neC . Then the measure of the angle A is

In a triangle ABC, right-angled at B, side BC = 20 cm and angle A= 30°. Find the length of AB.

In a triangle ABC, right angled at C, find the value of tan A + tan B in terms of the sides a,b,c.

Draw a triangle ABC with side BC = 7 cm, angle B =45 ^(@), angle A = 105 ^(@). Then, construct a triangle whose sides are 4/3 times the corresponding sides of Delta ABC.

In a triangle ABC, the sides b,c are given.If there is an error delta A in measuring angle A.Then side a is error delta a in the side a is

Construct a triangle ABC in which BC = 8 cm, angle B = 45° and angle C = 30° Construct another triangle similar to Delta ABC such that its sides are 3/4. of the corresponding sides of Delta ABC.
