16.5 pts Question 6 Find the value of x in the following squares: 18. 16. 17 18 1 X 16) 17) 18)

Answer 1

с solution: (16) LB = 90 2 A x B ДАВС - AB=BO (because AB CD is a square) A ABC is a right triangle. using pythagoras theorem - (AB)2 + (BC)2 (Ac)² (0)2 + (82)2 = (2) ² 2x2 24 % - 2 ge? = (19) A 18 DABC is a right triangle. x LB = gol B C A B = B c-a using pythagoras theorem -

= - x2 982 2 re A co (18) (AB)2 + (BC)? (AC)? (0)2 + (33) (18)2 2012 = 188 18 18 X 18 2 18x9 A ABC is a Right triangle. LB = 90'; AB=Bc using pythagoras theorem- (AB) + (80)2 = (AC) (1) 2 + (&)2 = (5)? .lt 1 1 26 С 2 - 2 - x² x² 12 a = 16. 12 982 17. 18. 2
