Answer:

Step-by-step explanation:

(x - 1)² - (y - 1)² has the form of a² - b² which is equal to (a - b)(a + b) where a = x-1 and b = y - 1

then

(x - 1)² - (y - 1)² = [(x - 1) - (y - 1)]×[(x - 1) + (y - 1)]

= [x - y]×[x + y - 2]

Answer:

$x=81\degree$

$y=99\degree$

$z=129\degree$

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees.

$\implies 51\degree+48\degree+x=180\degree$

$\implies 99\degree+x=180\degree$

$\implies x=180\degree-99\degree$

$\implies x=81\degree$

Use the exterior angles theorem to find y.

The exterior angle y is the sum of the two remote interior angles:

$y=51\degree+48\degree=99\degree$

The sum of angles on a straight line is 180 degrees.

$\implies z+51\degree=180\degree$

$\implies z=180\degree-51\degree$

$\implies z=129\degree$

every fourth visitor to a museum gets a free bumper sticker every tent visitor to the museum gets a free keychain which visitor

ioda

The 20th visitor will be the first to get both the key chain and the bumper sticker, I found this out by finding the least common multiple, or LCM, you do this by writing out the multiples of both 4 and 10, 4 8 12 16 20..... and 10 20 30... then you find the smallest number that both 4 and 10 have in common. I hope this helps, sorry if it doesn't.
