Please help! i think the answer is 12 but any verification would be greatly appreciated!
ANEK [815]

Answer:

13.9 or 14

Step-by-step explanation:

a^2 + b^2 = c^2

5^2 + 13^2 = c^2

25 + 169 = 197

square root 197 to get c

c = 13.9 (14 rounded up)

Helpful thing to note is that the hyptoenuse will always be longer than your "long side" of the triangle

Answer:

It has two solutions

Step-by-step explanation:

The system \frac{3}{4z}=\frac{1}{4z-3}   + 5

If we try to simplify the fractions applying the Lesser Common Factor

We obtain this:

12z-9=4z+ 5(4z)(4z-3)

From this equation, you can see a square term coming up, from where we can say that this system has two solutions

<u>Step-by-step explanation:</u>

A triangle consists of three sides, depending on the measurement of the sides, naming of the triangles can be varied.

If all the three sides are equal in length, it is said to be an equilateral triangle. Only one triangle can be formed using the measures of 7 in, 7 in, 7 in, that is all the three sides are same in measurement of 7 inches.
