Triangle N P O is shown. Line O N extends through point M to form exterior angle P N M. Angle N P O is 38 degrees. Angle P O N i
elixir [45]

The measure of the exterior angle PNM will be x < 77. Then the correct option is C.

<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.

More about the triangle link is given below.

Log7^x-log7^3=1 <br>if anyone can help me with this problem please help me
vagabundo [1.1K]
Log7 (x+3) - log7 (x-3) = 1
log7 [(x+3) / (x-3)] = 1
raise both sides to power of 7
(x+3) / (x-3) = 7
7x – 21 = x + 3
6x = 24
x = 4

Write an equation in point-slope form of the line that passes through the point (9, 0) and has a slope of m=−3
Softa [21]

Answer:

y=-3(x-9)

Step-by-step explanation:

Point slope form is y-y1=m(x-x1)

x1=9

y1=0

m=-3

plug it all in!

y-0=-3(x-9)

y=-3(x-9)

Hope this helps!

Help me solve this question
irga5000 [103]
The correct answer is 1.

So, circle the 0 after the equals sign because the equation does not equal 0.

Anything raised by the power of 0 is 1.

This is known as the zero exponent rule :)
