Step-by-step explanation:

2 × (First Angle + Second Angle) = 360°

14x + 26 = 180°

14x = 180 - 26

15, Evaluate 6 choose 4.

Novosadov [1.4K]

Answer: The required result is 15.

Step-by-step explanation: We are given to evaluate the following :

"6 choose 4".

Since we are to choose 4 from 6, so we have to use the combination of 6 different things chosen 4 at a time.

We know that

the formula for the combination of n different things chosen r at a time is given by

$^nC_r=\dfrac{n!}{r!(n-r)!}.$

For the given situation, n = 6 and r = 4.

Therefore, we get

$^6C_4=\dfrac{6!}{4!(6-4)!}=\dfrac{6!}{4!2!}=\dfrac{6\times5\times4!}{4!\times2\times1}=15.$

Thus, the required result is 15.
