There were 13,531 new products introduced last year. If 87% of the products introduced last year failed to reach their business

kvasek [131]

I'm assuming that since 87% failed, that would the remaining 13% was a success. If that assumption is correct, than we simply have to take:

.13 * 13531 = 1759.03 products were successful.

Find the value of x.

Brrunno [24]

Answer: x=133

Step-by-step explanation:

This is a hexagon that has a total of 720 degrees (which you can get by the formula of degrees = (# of sides – 2) * 180).

You first add up all your side:

150+130+97+120+90 +x = 587 + x

587+x = 720

x=133
