The angles in a triangle are
in the ratio 1:5:6. Work out the
angles in degrees.

The angles are 15,75,90

Step-by-step explanation:

Multiply the ratio by x

1x:5x: 6x

The sum of the angles of a triangle are 180

1x+5x+6x = 180

Combine like terms

12x = 180

Divide by 12

12x/12 = 180/12

x =15

Multiply by 15

1*15 : 5*15: 6*15

15: 75:90

12: 60: 72

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
