A circle is inscribed in a triangle `A B C` touching the side `A B` at `D` such that `A D=5,B D=3,if/_A=60^0` then length `B C` equals. 9 (b)`(120)/(13)`(c) `13`(d) `12`

A circle is inscribed in a A B C having side 8c m ,10 c ma n d12 c m as shown in Figure. Find A D ,B Ea n dC Fdot

9+|-4| is equal to: 5 (b) -5 (c) 13 (d) -13

Side B C of a triangle A B C has been produced to a point D such that /_120^0dot If /_B=1/2/_A , then /_A is equal to 80^0 (b) 75^0 (c) 60^0 (d) 90^0

Let aandb represent the lengths of a right triangles legs.If d is the diameter of a circle inscribed into the triangle,and D is the diameter of a circle circumscribed on the triangle,the d+D equals.(a)a + b (b) 2(a+b)(c)(1)/(2)(a+b)( d) sqrt(a^(2)+b^(2))

If a , b ,\ A are given in a triangle and c_1a n d\ c_2 are two possible values of third side such that c_1^2+c_1c_2+c_2^2=a^2 , then A is equal to 30^0 (b) 60^0 (c) 90^0 (d) 120^0

In a rhombus A B C D , if /_A C B=40^0, then /_A D B= (a) 70^0 (b) 45^0 (c) 50^0 (d) 60^0

In a quadrilateral A B C D , bisectors of angles A\ a n d\ B intersect at O such that /_A O B=75^0, then write the value of /_C+\ /_D

In a triangle A B C , if B=30^0a n d\ c=sqrt(3)\ b , then A can be equal to 45^0 (b) 60^0 (c) 90^0 (d) 120^0
