Complete the paragraph proof you can use a similar triangles formed by the altitude to write ratios for corresponding sides. Using ratios from large and medium triangles, C/A=__.This can be written as__=a^2. using ratios from the large and small triangles,__=B/E. This can be written as B^2= EC. By substitution A^2+B^2=___. You can then factor as A^2+B^2=C(F+E). From the large triangle you know (F+E)=__. So, A^2+B^2=C^2. By using substitution.

answer: give more info

step-by-step explanation:

16.9 times 2.85

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

i believe the answer is the polygon, heptagon.
