What is the perimeter of triangle ABC? Round each step to the nearest tenth. Please help me
Ad libitum [116K]

I would use the pythagorean theorem to find the lengths of each side. a² + b² = c².

Side AB is one we're looking for. If you make other right triangle with that same side you can see that one length is 4 and the other is 3. So, 4² + 3² = c² → 25 = c² → 5 = c. Side AB is length 5.

Side AC is another. Do the same with that side and you get that one length is 4 and the other is 3. (This is the same one as above) so side AC is length 5.

Side BC is the last one. One of the lengths is 1 and the other is 1 → 1² + 1² = c² → 2 = c² → 1.414213562 = c so side BC is approximately length 1.41.

Add each length up and you get a perimeter of roughly 11.4

Try this:
if given dx+e²ˣdy=0, then
dy=- \frac{dx}{e^{-2x}} \ =\ \textgreater \  \  \int dy=-\int e^{-2x}dx; \ =\ \textgreater \  \ y= \frac{1}{2}e^{-2x}+C;

Two different sized triangles have a scale factor of 2:3. If the hypotenuse ( the longest side ) of the bigger triangle measures
OlgaM077 [116]

Answer:

16 in

Step-by-step explanation:

The 3 part of the ratio represents 24 inches.

Dividing by 3 gives the value of one part of the ratio.

24 in ÷ 3 = 8 in ← value of 1 part of the ratio, thus

2 parts = 2 × 8 in = 16 in ← hypotenuse of smaller triangle
