Answer:
24cm, 28cm, 36cm
Step-by-step explanation:
Since the sides have a ratio of 6:7:9 we can connect them to the variable of x and find the sum of the sides for the perimeter:
P = 6x + 7x + 9x = 88
Combine like terms: 22x = 88
Divide by 22 on both sides: 22x/22 = 88/22
Solve for x: x = 4
6x = 6(4) = 24cm
7x = 7(4) = 28cm
9x = 9(4) = 36 cm
Answer:
x = 12
Step-by-step explanation:
(2x + 4) and (12x + 8) are same- side interior angles and sum to 180° , then
2x + 4 + 12x + 8 = 180
14x + 12 = 180 ( subtract 12 from both sides )
14x = 168 ( divide both sides by 14 )
x = 12
