In Fig. 1, ABC is a triangle in which AB = BC and `/_B = 40^@`, then `x=`

In Fig.6.59, ABC is a triangle in which angleABC<90^@ and AD_|_BC .Prove that AC^2=AB^2+BC^2-2BC.BD .

In Fig , ABC is a triangle in which angleABCgt90^(@) and AD bot CB, produced . Prove that AC^(2)=AB^(2)+BC^(2)+2BC.BD

ABC is a triangle in which AB = 40 cm, BC = 41 cm and AC = 9 cm. Then ortho-centre of Delta ABC lies________

In Fig . ABC is a triangle in which angleABClt90^(@)and AD botBC. Prove that AC^(2)=AB^(2)+BC^(2)-2BC.BD.

In fig., ABC is triangle in which angleABC > 90@0 and AD bot BC produced, prove that AC^2 = AB^2 + BC^2 + 2BC.BD . .

In the adjacent figure, ABC is a triangle in which angle ABC AC^2 = AB^2 + BC^2 -2BC. BD .

Construct triangle ABC in which AB=4.5 cm, BC =2.7cm and /_ B=54^(@)

In Fig.10.53,ABC is a right triangle right- angled at B such that BC=6cm and AB=8cm. Find the radius of its incircle.( FIGURE)

In the figure above, ABC is a right triangle and BC=AB , then find x^(@) .
