Question

how many digonals does a pentagon have​

Answer 1

Answer:

$\red { Number \: diagonls \: of \:a \: pentagon}\green {= 5}$

Step-by-step explanation:

$Number \: sides \: in \: a \: pentagon (n) = 5$

$\boxed {\pink { Number \: of \: diagonals = \frac{1}{2} n(n-3) }}$

$Number \: diagonls \: of \:a \: pentagon \\= \frac{1}{2} \times 5(5-3) \\= \frac{1}{2} \times 5 \times 2 \\= 5$

Therefore.,

$\red { Number \: diagonls \: of \:a \: pentagon}\green {= 5}$
