What is the perimeter of this triangle ⬆️

36 km

Step-by-step explanation:

We can use the Pythagorean theorem to find a

a^2 +b^2 =c^2

a^2 +12^2 = 15^2

a^2 +144=225

Subtract 144 from each side

a^2 =225-144

a^2 =81

Taking the square root of each side

a = sqrt(81) = 9

Then we need to find the perimeter

a+12+15

9+12+15

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
