How are the interior and exterior angles of a triangle related ?

2 answers:

Sample Response: The exterior angle, D, is supplementary to the adjacent interior angle, C. Together, they form a straight line, measuring 180°. The measure of the remote interior angles, A and B are equal to the measure of the exterior angle D.

The interior and exterior triangles are related because they are in the pyramid x + c = Triangle so thats how

Determine how long it will take an airplane to travel 2000 miles if it flies 200 miles per hour, 400 miles per hour, and 600 mil

AveGali [126]

I will use 'hr' to mean hour and 'hrs' to mean hours.

The airplane flies:

200 miles per hr

400 miles per hr

600 miles per hr

Average speed = Total distance ÷ total time

= (200 + 400 + 600)miles ÷ 3hrs = 400miles/hr

Time = Distance ÷ Average speed

= 2000miles ÷ 400miles/hr = 5hrs

What are the points of discontinuity y=(x-5)/x^2-6x+5?

ollegr [7]

$y = \frac{x - 5}{x^{2} - 6x + 5}$
$y = \frac{x - 5}{(x - 1)(x - 5)}$
$y = \frac{1}{x - 1}$

x - 1 = 0
+ 1 + 1
x = 1

#10: find angle x and y! Im struggling so much with this question please help a gurl out!

Answers:

x = 100

y = 25

==============================================================

Explanation:

Angle y and the 25 degree angle are corresponding angle. Because the lines are parallel, this means that y = 25

Check out the attached image. Using a red pen, I extended one of the lines to form a triangle. From the alternate interior angle theorem, we know that one of the angles of the triangle is 75 degrees (alternate interior angles are congruent). Again this stems from the fact that the lines are parallel.

I've also introduced the variable z to help find x. The angles x and z add up to 180 degrees since they form a straight line. So we need to find z before we can find x.

The triangle's angles 25, 75, z add up to 180. Let's solve for z

25+75+z = 180

100+z = 180

z = 180-100

z = 80

Use this to find x

x+z = 180

x+80 = 180

x = 180-80

x = 100
