Hey can someone please help me with this? I’d appreciate if you put steps down and the answer! Tysm.

x = 22cm

Step-by-step explanation:

Pythagoras Therom a^2 + b^2= C^2

Opposite the right angle is x at the bottom which is the hypotenuse. you only need to work out the bottom triangle so forget the top.

18/2=9 for the bottom length.

9^2 + 20^2 = 481^2 (opposite of squaring)

square root 481 = 21.9317121 rounded up would be 22cm x= 22cm

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
