A triangle has two sides that are 8cm and 13cm. What could be the length of the triangles third side

Nikitich [7]

Answer:

5 < x < 21

Step-by-step explanation:

The sum of the shorter sides is greater than the longest side.

If 13 is the longest side:

x + 8 > 13

x > 5

If x is the longest side:

8 + 13 > x

21 > x

Therefore, the third side is any number between 5 and 21.

Exercise

Maurinko [17]

X - nominator
y - denominator

$\frac{3x}{y+12}=\frac{3}{4}\\
\frac{x+7}{3y}=\frac{1}{2}\\\\
3(y+12)=12x\\
2(x+7)=3y\\\\
3y+36=12x\\
2x+14=3y\\\\
2x+14+36=12x\\
10x=50\\
x=5\\\\
3y=2\cdot5+14\\
3y=10+14\\
3y=24\\
y=8\\\\
\frac{x}{y}=\boxed{\frac{5}{8}}$
