Yo sup??
we know that the sum of all the angles of a triangle is 180
therefore
11x+7x+90=180
18x=90
x=5
exterior angle formed on the ground=180-11x
=180-55
=125
Hope this helps

Step-by-step explanation:
Given that Saguaro cacti are large cacti indigenous to thesouthwestern United States and Mexico. Assume that thenumber of saguaro cacti in a region follows a Poisson distribution with a mean of 280 per square kilometer.
a) Mean number of cacti per 10,000 square meters=280*10000 = 2800000
b) P(no cacti in 10000) sq m = P(X=0) for Poisson with parameter 2800000
= 0
(almost uncertain event)
c) Area of a region such that the probability of at least twocacti in the region is 0.9.

We get this is possible if mean = 8.4 for Poisson
i.e. region should have area as

Answer:
<h2>A)15</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>let's solve:</h3>
parimeter of a square:4a
according to the question

divide both sides by 4:

cancel 2 from both sides:

divide both sides by 8
