Here you have x + 3x + 72 = 180. By isolating the variable by dividing on both sides, the answer is x = 27

Answer:

18, 54, 108

Step-by-step explanation:

Let the first angle is ‘x’

Second angle =3x

Third angle=2(3x)=6x

Sum of the three angles of a triangle =180 degrees

x+3x+6x=180

x=18

The first angle is 18,second angle is (3*18)=54.third angle is (6*18)=108

The angles are 18,54 and 108 degrees

Kate had a sum of money,she spent 1/8 of the money on a skirt and the remaining amount on a handbag,the skirt cost $16,how much
tiny-mole [99]

Answer:

$18.28

Step-by-step explanation:

Step one:

given data

Kate had a sum of money,she spent 1/8 of the money on a skirt and the remaining amount on a handbag

let the total money be x

so  mathematically

x-1/8*x= 16

solve for x

x-x/8= 16

8x-x/8= 16

7x/8=16

cross multiply

7x= 8*16

7x=128

divide both sides by 7

x=128/7

x=$18.28
