Angle W is congruent to angle Z the measure of angle W is 5x + 10
The measure of angle Z is 55 degrees

x = 9

Step-by-step explanation:

If  the question is find x:

5x + 10 = 55

5x = 45

x = 9

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
