How do I solve this geometry problem ??

x = 20

Step-by-step explanation:

sum of interior angles of 5 sided polygon: 180 x (5-2) = 540

7x + (4x + 5) + (5x - 5) + (6x + 10) + (4x + 10) = 540

26x + 20 = 540

26x = 520

x = 20

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
