A wire of length 20cm is cut into two pieces, each of which is bent into a square, (a) If the length of the side of one square is x cm, show that the length
of the side of the other square is (5 - x) cm.
The total area of the two squares is 14.5cm
(b) Find the lengths of the two pieces of wire.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

d. all of the above

step-by-step explanation:

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
