We can use the fact that the addition of all four internal angles of a quadrilateral must render $360^o$ . Then we can create the following equation and solve for the unknown "h":

$2h+2h+h+h = 360^o\\6h=360^o\\h=60^o$

Therefore the angles of this quadrilateral are:

$120^o,\,120^o,\,60^o,\,\,\,and\,\,\,60^o$

if a lake has high alkalinity, what is closest to the probability that the lake also has a shallow depth?

never [62]

Answer:

0.22

Step-by-step explanation:

Probability distribution is the function which describes the likelihood of possible values assuming a random variable. The alkalinity of lake is determined by dividing the high shallow depthness by the total of lake alkalinity. The shallow depth is 209 and the total alkalinity of the lake is 966. By dividing the depthness with alkalinity we get 0.22.

209/966 = 0.219

approximately 0.22
