Question

help?? I don’t really need answers I just need an explanation on solving these kind of math stuff lol (I did the first two by myself feel free to tell me if I got em wrong)

Answer 1

yes you are right

Explanation:

1) Scale 36/27 = 1.33333333 = 1 1/3 Then 20/ 1.33333333 = 15 so yes you are on right track as the shapes are congruently placed side by side for type question and note you have remembered to use the lengths with lengths and widths with widths- just remember to do fold the shapes in your head to determine this or draw dotted line to emphasise the congruency as it exposes each mid point and emphases length fro width or with triangles hypotenuse from next order of longer side within the triangle to triangle emitting smaller side from diagram on each 2) Scale = 1.75 For the second one 42/ 24 = 7/4 = 1.75 and 28/1.75 = 16 is also correct

Answer 2

So to get the hypotenuse it’s the square root of a.sq+b.sq. So if a triangle had an a side of 1 inch and a b side of 1 inch than the answer would be around 1.414. If you want to get a or b just reverse the equation.
