Answer:
x = 16.8
Step-by-step explanation:
The ratio of corresponding sides is equivalent to the ratio of the perimeters.
Then using proportion
= 
( cross- multiply )
5x = 84 ( divide both sides by 5 )
x = 16.8
Answer:
(36,72)
Step-by-step explanation:
The x (3) is half of y (6) so following that pattern (36,72) is the only option.
Assuming those are the legs of the triangle and that you need to find the hypotenuse... I would use the formula: a^2+b^2=c^2
It doesn't matter what a and b are, just fill it in.
25^2+35^2=c^2
625+1225=c^2
1850=c^2
Take the square root of 1850, it isn't a perfect square so I got: 43.01.
If you want, just round it to 43, idc.
So, if I were to check my work, I would need to remember that the hypotenuse is the longest side.
Since 43 is the hypotenuse, it is the longest side.
It’s plus 9 so the next number should be 32
