15. In a similar figure the sides are proportional. So you have to say which ratio of sides is also proportional or which sides are equal to the fraction 44/35.2
it would be c because :
44/35.2 = 132/105.6
16. same thing with similar triangles. if the length of sides are similar then so is perimeter. So so we find the ratio of the side lengths. We we know sq is 6 and qt is 24. So st is 30. So so the line st and sq are matching and similar so we compare their lengths and get a ratio
sq * x = st
6 * x = 30
x = 5
So so the perimeter is 5 times more than small triangle so
5 * 20 = 100
17.similar side is 0.5 and 3.6 so ratio is 3.6/0.5. we know she is 1.8 talk so
1.8 * 3.6/0.5 = 12.96
Please put the selections. I can't tell you what isn't true if you don't.
T = How tall they are.
Robin = 180
His brother = x cm shorter
T = 180 - x
