<h3>What is the triangle?</h3>

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

Triangle NPO is shown.

Line ON extends through point M to form exterior angle PNM.

Angle NPO is 38 degrees.

Angle PON is 39 degrees.

Let the exterior angle PNM is x degrees and the interior angle PYO be y.

Then we have

38 + 39 + y = 180°

y = 103°

And we know that the sum of interior and exterior angle is a triangle is 180 degrees.

x + y < 180

103 + x < 180

x < 77

Then the correct option is C.

A city that had 40,000 trees started losing them at a rate of 10 percent per year because of urbanization.

Answer:

t = 13.1576 years

Step-by-step explanation:

The situation can be modeled as

P = Po.(1-r)^t

Where

t is the years transcurred

Po is the initial amount

r is the rate of change

Po = 40000

r = 10% equivalent to 0.1

Now

A quarter of the original amount

(1/4)*Po = Po.(1-r)^t

(1/4) = (0.9)^t

t = 13.1576
