Question

calculate x in each of the following figure​

Answer 1

Answer:

Taking triangle I :

H = 55 cm

P = 44 cm

B = ?

By Pythagoras Theorem :

(55)²=(44)²+(B)²

= (B)²= 3025-1936

= B = √1089 cm²

= B = 33 cm

Taking Triangle II :

H = ?

P = 56 cm

B = 33 cm (previously solved)

By Pythagoras Theorem :

(H)²=(56)²+(33)²

= H=√4225 cm²

= H = 65 cm

Taking Triangle III :

H = 65 cm

B = 63 cm

P = x

By Pythagoras Theorem :

(65)²=(63)²+x²

= x=√4225-3969 cm²

= x = 16 cm
