The ratio of the sides of a triangle is 2:4:9. If the perimeter is 165 inches, what is the length of the longest side?

99inches

Step-by-step explanation:

The ratio of the sides of a triangle =2:4:9.

perimeter = 165 inches,

Total ratio= 2+4+9=15

perimeter = 165

Divide the perimeter by total ratio

165/15=11

Each of the sides

= (2×11) =22

(4×11) =44

(9×11)=99

the length of the longest side= 99inches

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

answer: 40392

step-by-step explanation:

10098 x 4 = 40392
