In a △ABC it is given that /_B = 37^(@) and /_C =29^(@) . Then, /_A = ?

In the figure, ABC is a triangle in which /_C=90^(@) and AB=5cm . D is a point on AB such that AD=3cm and /_ACD=60^(@) . Then the length of AC is

ABC is a Deltain which /_B gt 90^(@)" and "AD bot CB produced. Prove that AC^(2)= AB^(2)+BC^(2)+2BC*BD .

B. Write 'true' or 'false' : In angle"ABC", angle"B" = 90^(@) , If AB = BC, then angle"C" =60^(@) .

In the given Delta ABC, It is given that /_B=90^(@),AB=24cm and BC=7cm Then cos A=?
