Question

in triangle AbC if a=3cms b=4cms angke c=90 find side c hence find cos A cos B cos C​

Answer 1

Answer: 5cm

Step-by-step explanation:

so here we should first draw the rough diagram of it

then put the cms and degrees as we look it it would be a right angles triangle

so we should put AB=4cm BC = 3cm  angle C = 90 degree so as we look we have to find the c according to pythagoras theorem  c = root of a sq + b sq so it will be c = 9 + 16 so the answer will be root of 25 = 5 answer is 5cm soo when literally two sides and one 90 degree is given u can understand it is a right angles triangle and u should apply the pythagoras theorem. ok
