Use an algebraic equation to solve the problem. the sides of a triangle are in the ratio 3 : 4 : 5. what is the length of each side if the perimeter of the triangle is 90 cm?
a. 10.5 cm, 11.5 cm, and 12.5 cm

b. 22.5 cm, 30 cm, and 37.5 cm

c. 7.5 cm, 11.5 cm, and 32.1 cm

d. 19.3 cm, 25.7 cm, and 32.1 cm

The answer is the option B

Step-by-step explanation:

Let

a,b,and c the length sides of the triangle

we know that

------> equation A

-----> equation B

-----> equation C

Substitute the equation B and equation C in the equation A

solve for b

Substitute the value of b in the equation B

Substitute the value of b in the equation C

the answer is simply just 6n add the two together as they have an n

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
