If the perimeter of a rectangular picture frame must be less than 200 in., and the width is 36 in., what must the height h of th
Zigmanuir [339]
The perimeter is 2 width + 2 length. So 200 = 2(36) + 2 length and that simplies to 200 = 72 + 2 length. Now we have to subtract 72 from both sides to get the 2 lengths alone. So 128 = 2 length. Finally, we divide both sides by 2 to get the length alone. 64 = length. Now since the perimeter has to be less than 200 inches than the length can be any number less than 64. Hope this helps and if so please leave a good rating and thanks and maybe even brainliest answer. Thank you I really appreciate it. Have a nice day!

nignag [31]
Hello!

First you have to find the ratio

To find this you put the sides of the triangles in a ratio and simplify it

Make sure you do the same side on each triangle

12 : 8 
6:4
3:2

The ratio is 3:2

We do not know all three sides so we can use the SSS postulate

This tells use the answer is the SAS postulate with a ratio of 3:2

The answer is D) SAS; 3:2

Hope this helps!
